History
Église Saint-Sulpice de Seraincourt is a Roman Catholic parish church in France, built and developed through several medieval and later architectural phases. Its origins are uncertain, but the oldest surviving parts probably belong to approximately 1110–1125, within the late eleventh or first third of the twelfth century. The building combines Romanesque, Early Gothic, and later Gothic elements, and its history is closely connected with the Premonstratensian religious order.
Foundation and Premonstratensian administration
The church is dedicated to Saint Sulpice the Pious, bishop of Bourges and chaplain to Clotaire II, who lived from 576 to 647. The earliest church probably had a cruciform plan. Its choir and the base of the bell tower appear to belong to a single building campaign around 1110–1125.
During the Ancien Régime, the former system of French administration, the parish belonged to the Archdiocese of Rouen, the archdeaconry of the Vexin, and the deanery of Meulan. Between 1170 and 1176, Archbishop Rotrou of Warwick gave the parish to Saint-Josse Abbey at Dommartin. The abbey was a Premonstratensian institution, whose canons combined communal religious life with pastoral work, including parish ministry.
Premonstratensian canons served the church from 1175 until the suppression of Saint-Josse Abbey and its priories during the French Revolution in October 1791. They established a rural priory-curacy at Seraincourt. A priory-curé administered the parish with the assistance of two other canons until the middle of the seventeenth century, when declining revenues left only the prior-curé. Évrard, appointed in 1760, was the final holder of that office.
Seraincourt maintained close links with the nearby Saint-Pierre Priory at Gaillonet, founded by about 1163. A canon from Gaillonet officiated as deacon at major ceremonies. In 1269, the Saint-Jean chapel at Rueil was transferred to the Premonstratensians, extending the network of religious institutions connected with the parish.
Medieval enlargement
The church developed beyond its earliest Romanesque form. The north transept arm was probably rebuilt and a north chapel was added beside the choir during the later twelfth or early thirteenth century. Their funding is attributed to the Premonstratensians after their arrival, although the exact sequence of construction remains uncertain. The rib vaults may also have been introduced in a secondary phase.
During the second half of the twelfth century, arcades were opened through the choir’s side walls. This work removed the original side windows from the interior arrangement, although traces of the earlier openings remain in the masonry. A large two-bay chapel was built south of the bell-tower base and choir during the first third of the fourteenth century, probably before the economic recession and the Hundred Years’ War. It may have replaced an earlier south transept arm.
The south arch of the bell-tower base was widened in the fourteenth century. The choir’s east window was reopened or altered during the late fifteenth or early sixteenth century, when its present Flamboyant Gothic design took shape. Flamboyant Gothic was a later medieval style known for flowing, flame-like tracery and complex window patterns.
An earlier south porch and the sacristy were added at uncertain dates. The porch survived until the nineteenth-century rebuilding of the nave. The church’s exterior consequently came to represent four principal periods, although its complex history is more fully understood from the interior.
Revolutionary and nineteenth-century changes
The French Revolution replaced the former parishes with communes. Seraincourt absorbed Gaillonet and Rueil, while the Saint-Pierre Priory, the Saint-Jean chapel, and the presbytery or priory in the village center were sold as national property. The priory disappeared, and the chapel lost its religious function.
Catholic worship was suspended during the Terror, the most repressive phase of the Revolution, between autumn 1793 and spring 1795. Worship resumed under the Concordat of 1801, and the church became part of the Diocese of Versailles, created for the former department of Seine-et-Oise.
Roof and carpentry work was completed throughout the church in 1824. By 1850–1854, however, the building was considered damp and unhealthy. Its roofs were deteriorating, voussoirs, the wedge-shaped stones forming its arches, were loosening, vaults were threatened, and the nave vaults showed serious movement. Architect Blondel therefore proposed rebuilding the nave and removing the south porch.
The old nave was dismantled and replaced in 1863. Reusable medieval rubble, sculpted blocks, carpentry elements, tiles, and the colonnettes from the former western portal were incorporated into the new structure. The new nave was shifted 80 centimeters north so that its axis aligned with the bell-tower base and choir. In 1867, the vault over the bell-tower base was rebuilt on the springings of the earlier vault and made identical to it. The south chapel floor was lowered by 12 centimeters, incomplete window tracery was restored, and all the stained glass was replaced. Two windows in the north chapel and north transept were blocked with hollow bricks in 1868.
Protection, damage, and restoration
The cemetery surrounding the church was transferred outside the village in 1884. Exhumation and excavation associated with the transfer later contributed to foundation problems in the north transept. The church was entered in the supplementary inventory of historic monuments in 1926 and classified as a historic monument by order of 7 January 1930.
A new clock was installed in 1920. In 1928, rainwater reached cavities left by the cemetery transfer and infiltrated the north-transept foundations. Serious settlement followed. The northwest buttresses leaned outward and detached from the walls. Restoration began in 1931 with partial dismantling of the north-transept vault and continued until 1935. The unusable stair turret installed between the nave and south chapel in 1863 was demolished, while an older stair turret was restored and fitted with new Saint-Maximin stone steps.
Fighting and bombardments in August 1944 seriously damaged the church, particularly the vaults of the south chapel. All of the stained glass was destroyed or broken. During bell-tower restoration in 1946, a bronze bell cast in 1790 was stolen. Postwar restoration was first directed by Robert Camelot and later by Sylvain Stym-Popper. Since the planned figurative windows could not be afforded, the Max Ingrand workshop supplied two decorative windows and twelve diamond-pattern windows, installed in 1953–1954.
The sacristy ceiling and roof were repaired in 1987. A restoration program prepared in 1993 led to work on the nave roof and lower walls between 1995 and 1998 under Pierre-André Lablaude. When the Diocese of Pontoise was created in 1966, Saint-Sulpice was the only church in Val-d’Oise to remain in the Diocese of Versailles. After a consultation of local residents in 2016, it joined the Diocese of Pontoise on 1 September 2017 and became affiliated with the Avernes and Marines parish.
Remains
The church is regularly oriented, although its axis deviates 11 degrees southward toward the east. Its surviving plan consists of a three-bay single nave, a square bell-tower base at the crossing, a one-bay choir, a deep north transept arm, a north chapel beside the choir, and a two-bay south chapel. A sacristy occupies the angle between the north transept and north chapel, while an internal stair turret stands in the nave’s northeast corner. The choir and both chapels have flat east ends aligned on the same line.
The nave
The interior length is 25.90 meters, including 15.40 meters for the nave, 5.90 meters for the bell-tower base, and 4.60 meters for the choir. The nave is 7.00 meters wide and reaches approximately 7.53 meters at its highest point. Built in 1863, it has three hollow-brick groin vaults covered with plaster and render. A groin vault is formed by the intersection of two vaults. Two slightly pointed transverse arches divide the space into three bays. Their square, chamfered profiles are 44 centimeters across and merge directly into engaged piers.
The nave walls are plastered and whitewashed, and the floor is paved with Beauvais tiles. Its windows are simple lancets, each with internal and external splays, approximately 90 centimeters wide and 270 centimeters high. The west wall is blind. The present western portal was moved from the south side of the former nave, where the entrance had occupied the first bay.
Medieval material remains visible in the exterior of the rebuilt nave. Medium-sized stone surrounds the windows, while sculpted diamond-point blocks, old rubble, and some former roofing materials were reused in the walls. The lower courses are 70 centimeters thick and the upper courses 55 centimeters thick. The buttresses are stylistically closer to those of the fourteenth-century south chapel than to the flat Romanesque buttresses of the north transept.
The bell-tower base and choir
The square bell-tower base measures only 3.20 meters internally on each side. Its west, north, and east arches are 2.55 meters wide between the piers. The southern opening is wider because two engaged columns were removed. The four original arches were identical, semicircular, and formed with two rolls. Their lower rolls contain two large toruses separated by a narrow interval, while the upper rolls have one torus on each side. Engaged shafts support the lower rolls, and detached colonnettes with capitals support the upper ones.
Twenty capitals survive from an original group of twenty-four. Their square abaci carry Romanesque ornament, including zigzag lines. The baskets display angle volutes, masks, water leaves, acanthus leaves, foliage, interlace, scrolling foliage, tongues of flame, and occasional human or monstrous heads. Most of the original vegetal claws at the bases have disappeared. The bell-tower base has a groin vault reconstructed in 1867. Its bell opening is no earlier than the fifteenth century, and the socles are partly buried by a floor raised approximately 30–40 centimeters.
The nearly square choir is 4.10 meters wide, making it 80 centimeters wider than the bell-tower base. It retains an original barrel vault made of regularly laid longitudinal stonework. A barrel vault is a continuous semicircular or segmental vault. The surface is whitewashed and painted to imitate ashlar. The intermediate transverse arch has the same profile as the lower rolls of the arches around the bell-tower base, with two large toruses separated by a narrow fillet. It rests on engaged capitals, including a southern capital carved with a bearded human head and a northern capital preserving the impression of a similar sculpture.
Large slightly pointed arcades were opened through the choir’s pre-existing side masonry. The northern arcade is 4.10 meters wide, while the southern arcade is slightly narrower and has an intrados painted with heraldic motifs. The openings cut through earlier semicircular windows with internal splays. The southern second bay was enlarged, and the northern windows remain visible from the north chapel.
The north transept and chapel
The north transept is unusually deep, measuring 8.00 meters from north to south and 3.90 meters across. Its western portal is 111 centimeters wide, with jambs 245 centimeters high. A plain tympanum, the panel within a portal arch, also serves as the lintel. Above it, an archivolt, or moulded band following the curve of an arch, is formed by voussoirs and a diamond-point or sawtooth cordon.
The date and original position of the portal remain uncertain. It may belong to the earliest church, may have been shifted approximately half a meter westward, or may have been constructed with the present north transept. The transept and north chapel are covered by rib vaults, which are vaults carried by intersecting structural ribs. Their ribs have a thin fillet between two toruses and rest on detached colonnettes with diagonally positioned crocket capitals. The vaults lack dedicated formerets, and the north transept’s undecorated keystone is formed simply by the crossing ribs.
The north transept and chapel contain Early Gothic lancets with slightly pointed arches, external splays, and diamond-point cords. Their walls use rubble and medium-sized stone, with some areas rendered. Two stepped buttresses reinforce each exterior angle. The north transept’s eastern window is partly blocked, and the north chapel’s northern window is also blocked and markedly off-axis. The sacristy’s lean-to roof conceals the north chapel’s northern window and the transept’s east window.
The north transept cornice survives best on the east side. It consists of a tablet resting on carved masks or abstract motifs, with elongated beveled ovals between the modillions. The western cornice is largely demolished, while the northern section is concealed by the sacristy roof. The sacristy occupies the angle between the transept and chapel and has a lean-to roof. Replacing that roof with a flat roof would reopen the two blocked windows.
The south chapel
The south chapel is the most recent of the eastern compartments and consists of two homogeneous bays. It measures 8.98 by 5.60 meters and reaches 8.26 meters at its highest point. Its four large windows make it the most spacious part of the church, with an area nearly half that of the nave. The southern elevation is rigorously symmetrical in its dimensions, corner buttresses, and central buttress, although the arrangements of the windows differ.
Each bay has two pointed windows. The first bay has windows with two trefoiled lancets, while the second has three-lancet windows. Their tracery includes quatrefoils, small oculi, a large oculus, trefoils, and open spandrels. Some of the tracery was restored in 1867 after earlier partial blocking. The replacement stained glass was destroyed or broken in 1944. The windows are surrounded by hollows and have sharply chamfered mullions without capitals or bases.
The two vaults have torus-moulded formerets, prominent torus ribs, and small carved bosses with simple leafy rosettes. The ribs rest on groups of three colonnettes with elongated crocket capitals and polygonal abaci. This support system anticipates the undulating piers of Flamboyant Gothic, since the colonnettes are separated by hollows rather than embedded in stepped piers. Many capitals are damaged. A surviving piscina, a liturgical basin for washing sacred vessels, is set into the east wall and indicates the chapel’s original use for Eucharistic celebrations.
Roofs and bell tower
The roofs do not fully reproduce the internal plan. The choir and north chapel share one gabled roof, while the two south-chapel bays share another roof with a south gable. The nave and north transept have perpendicular double-pitched roofs with west and north gables. The east gable is not original, and the roof space preserves the remains of a former small saddleback roof. The large gables partly obscure the bell tower.
The bell tower is a saddleback tower, meaning that two sloping roof planes meet at a ridge rather than forming a pointed spire. An intermediate level 1.80 meters high is reached by a thirty-nine-step spiral staircase from the nave’s northeast corner. The belfry, the part of the tower containing the bells and their supporting frame, currently accommodates a modern frame intended for one bell.
Each face of the belfry has two semicircular openings without sound shutters. Their exterior decoration consists of torus surrounds suggesting colonnettes, capitals with angle volutes at impost level, upper archivolts, and additional colonnettes near the corners. Each face ends in a cornice supported by eight notched stones and seven modillions. The modillions carry mainly abstract horizontal or vertical fluting. The plain gables each have a rectangular opening. The tower has no ceiling, corner squinches, or provision for an octagonal stone spire.
Furnishings and commemorative objects
The church retains a polychrome wooden statue of Saint Sulpice, 118 centimeters high and dated to the twelfth or thirteenth century. The bishop wears a mitre, a large red chasuble, a green dalmatic, an alb, and a stole. The forearms and hands are missing, and an oblique split runs from the neck toward the left arm.
A bronze bell cast in 1877 measures 125 centimeters in diameter and 105 centimeters high. Named Jeanne Marie Ivonne, it was cast by Mahuet of Dreux. A foundation plaque commemorates Claude Henri Lecointre, who died on 12 September 1823 aged seventy-seven. His bequest assigned half of its value to maintaining objects used in worship and half to educating boys and girls from poor families, in return for a monthly Mass for his soul.
The interior contains Stations of the Cross paintings and a painting of the Sacred Heart of Jesus, given in 1879 by Franz Genthner, a commander of the Order of Isabella the Catholic and former intendant-general of the court of Parma. He died at his property in Rueil on 15 April 1893. The former Virgin altar, shortened and placed against the nave’s south wall, is tomb-shaped and bears a medallion of the Agnus Dei on the Book with Seven Seals, surrounded by rays.
The eighteenth-century high altar is made of carved oak in the form of a tomb. Its central bas-relief shows a reed branch and an olive branch tied together within a crown of thorns. An eighteenth-century painting depicts Saint Sulpice as a thaumaturge. A polychrome wooden bust of Saint Peter from Gaillonet Priory formerly stood beneath a south-chapel window, but it disappeared after the damage of 1944.
