History
The Collegiate Church of St. Mary and St. Alexius is a Roman Catholic church in Tum, Poland, built by the Polish Church in the Romanesque period during the twelfth century. Located near Łęczyca, it served both religious and defensive purposes and remains closely associated with the medieval history of the region.
Monastic origins and Romanesque construction
Older research placed the foundation of a Benedictine monastery here around 997, associating it with Boleslaus I and Saint Adalbert. More recent interpretations date the monastery no earlier than the second half of the eleventh century, possibly during the restoration of the Piast monarchy under Casimir the Restorer. The Piasts were Poland’s first ruling dynasty, while Casimir was the ruler linked with the recovery of the Polish monarchy after a period of political and ecclesiastical crisis.
The monastery was probably relocated before its buildings were demolished to make way for the present church. Construction of the Romanesque church probably began around 1149 on the initiative of Janik, Archbishop of Gniezno. It was consecrated on 21 May 1161, perhaps before all the work had been completed, in the presence of Polish bishops, princes, and senior church officials. The church inherited the monastery’s dedication to the Blessed Virgin Mary and Saint Alexius, a Christian ascetic traditionally associated with renunciation and pilgrimage.
Its partly fortified form gave the church a role beyond worship, probably allowing it to shelter people from the surrounding settlement. The building resisted the Mongol invasion of 1241. During Pentecost in 1293 or 1294, Lithuanian forces led by Vytenis captured the church and settlement. Some refugees who had taken shelter inside were enslaved, while others were killed or died when the church and nearby settlement were burned.
Medieval collegiate use and rebuilding
A chapter of clerics served the church, making it collegiate rather than a monastery church served only by monks. Between 1181 and 1547, twenty-one provincial synods, traditionally known as the Synods of Łęczyca, were held there. These gatherings helped establish the church as an important ecclesiastical meeting place in medieval Poland.
Fourteenth- and fifteenth-century alterations changed the galleries, supports, sanctuary, side-aisle vaults, and damaged masonry. Łęczyca was attacked by the Teutonic Knights in 1331, and the collegiate church remained ruined for several decades. A fire in 1473 led to further rebuilding, completed in 1487. Pointed Gothic arches, brick piers between the nave and aisles, and other Gothic changes survived into later periods.
Renaissance and Neoclassical transformation
A Renaissance porch was added before the main entrance in 1569 to protect the earlier Romanesque portal. The interior was also furnished with plasterwork and frescoes. Between 1765 and 1785, Primate Łubieński initiated a major remodelling in the Neoclassical style, financed by Bishop Kajetan Sołtyk and directed by the architect Efraim Szreger.
This eighteenth-century work substantially changed the towers, nave, western façade, gables, windows, and interior. The towers received Neoclassical caps, the gallery arcades were blocked, and the inter-nave piers were encased. The outer walls of the side aisles at gallery level were lowered by two metres to reduce their weight. In 1818 or 1819, Alexander I of Russia ordered the dissolution of the Łęczyca chapter. The church lost its collegiate status and served as a parish church until 1915.
War damage, reconstruction, and renewed status
The church was damaged again during the Swedish invasion of 1705 and suffered catastrophic destruction during the Battle of the Bzura in September 1939. A German observer used the northern tower to direct artillery fire. Polish shelling destroyed the tower and started a fire, while later bombing by the Luftwaffe or Polish forces damaged the walls, roof, ceilings, and furnishings. The church was left roofless, and rubble covered much of its remaining equipment.
Reconstruction began in 1947 under Jan Koszczyc Witkiewicz, following the conservation principles of Jan Zachwatowicz. Although demolition had initially been considered because of the scale of the damage, the church was rebuilt as an important example of Romanesque architecture. The work continued for several years, and the building returned to religious use after its three altars were consecrated in 1961. Later restoration removed much of the Gothic and Neoclassical fabric in an effort to recover a simpler Romanesque appearance, while some Gothic elements in the side aisles were retained. Baroque plasterwork, decoration, the high altar, and epitaphs were removed during interior work that began in 1952.
Restoration in 1954 revealed foundations of the earlier Benedictine monastery beneath the church and uncovered a well-preserved twelfth-century wall painting in the western apse. From 1995 to 2008, comprehensive conservation addressed drainage, structural problems, architectural and sculptural fabric, and wall paintings. On 25 March 1992, the parish entered the newly established Diocese of Łowicz, and the church became an archicollegiate church, a collegiate church with elevated ecclesiastical rank. The Łęczyca chapter was re-established in 1993.
A relic of Saint Adalbert arrived from Gniezno in 1999. In 2000, Bishop Alojzy Orszulik established the church as the diocesan sanctuary of Saint Adalbert, bishop and martyr. In 1967, celebrations marking the millennium of the Christianization of Poland concluded at Tum, where Karol Józef Wojtyła, then Cardinal and Bishop of Kraków and later Pope John Paul II, celebrated Mass. A ceremony for the 850th anniversary of the consecration took place in 2011, when President Bronisław Komorowski and Apostolic Nuncio Archbishop Celestino Migliore unveiled a memorial stone. The church received designation as a Polish Historic Monument in 2022 and also has formal protection under Polish heritage law.
Remains
The church is an encastellated Romanesque basilica, a longitudinal church with a higher central nave and lower side aisles. It stands on a former islet or raised area once surrounded by wetlands and marshes. The building is arranged around a central nave, side aisles with galleries, a twin-tower western façade, and apses at both the eastern and western ends. Granite blocks, sandstone, and fieldstone form most of the masonry, while brick and reinforced concrete belong mainly to later repairs and reconstruction. The walls use opus emplectum, a technique in which two outer faces enclose a rubble-filled core.
Entrances and fortified elements
Romanesque portal and Renaissance porch
The main northern portal dates from the first half of the twelfth century. Its sculpted Romanesque tympanum survives beneath the sixteenth-century Renaissance porch, which was built in 1569. The porch protects the earlier entrance while forming one of the clearest visible layers in the church’s architectural history.
Western towers
The western towers and other parts of the church retain evidence of its fortified character. Round turrets were added at the eastern end during the twentieth-century reconstruction. A local legend says that dimples in the stonework at the edges of the towers are claw marks made by the devil Boruta while trying to overturn them.
Interior spaces and later alterations
Galleries, sanctuary, and side aisles
Medieval alterations reshaped the internal arrangement. In the western apse, a wall was built beneath the gallery arcade to create a chapter house. Openings in the eastern part of the galleries were blocked, lengthening the presbytery, and a bay of the southern aisle was enclosed for use as a sacristy. Damaged walls, including the window wall of the main nave, were partly rebuilt in brick. The side-aisle vaults were changed to cross-ribbed vaults, which are supported by intersecting ribs.
The eighteenth-century remodelling encased the inter-nave piers and altered the gallery arcades, while later conservation removed much of this work to restore the building’s Romanesque character. The rebuilt ceiling over the main nave is made of concrete to stabilize the old walls. Reinforced-concrete trusses support the roof. Because the weakened walls could not safely carry the intended Roman roof tiles, the covering was first changed to shingles and later to copper sheet.
Western apse painting
In the conch of the western apse beneath the gallery is a well-preserved twelfth-century Romanesque polychrome showing Christ Pantocrator, the Christian image of Christ as universal ruler. Its discovery during the 1954 restoration added an important surviving element to the church’s medieval interior.
Archaeological remains and furnishings
Benedictine foundations and early settlement
Foundations of the earlier Benedictine monastery lie beneath the church. To the southwest are remains of a nearby early medieval fortified settlement, including a mound and visible traces of the settlement burned during the medieval destruction.
Saint Adalbert memorials
A relic of Saint Adalbert is kept in a church-shaped reliquary, a container made to house a sacred relic, placed in the high altar. The main nave also contains an altar dedicated to him, designed by A. Koss in 2000. An oak dedicated to Saint Adalbert was planted in the surrounding garden in connection with the arrival of the relic.
Adjacent church and surviving furnishings
A small wooden Church of Saint Nicholas stands beside the collegiate church. Inside the main church is a bronze cast of a crucifix made by Józef Gosławski in 1943. The organ has fourteen stops and one manual.
