History
Burg Friedestrom is a former Electoral Cologne territorial and customs castle in Zons, Germany, built and developed by the archbishops of Cologne from the thirteenth century onward. It secured the Rhine toll collected at Zons and helped defend Electoral Cologne, the territorial state governed by the archbishops of Cologne, against the Counts and later Dukes of Berg.
From royal estate to fortified stronghold
A manorial estate of the Cologne archbishopric stood at Zons by at least the twelfth century. The property had previously been a Frankish royal estate and became one of the twelve table estates belonging to the Cologne archbishop. In the thirteenth century, Archbishop Konrad von Hochstaden probably expanded it into a fortified stronghold, or castrum, amid conflicts between Electoral Cologne, which held the lordship, and the Counts of Jülich, who held the advocacy rights connected with the estate. The exact position and appearance of this earlier fortress remain uncertain.
After Archbishop Siegfried von Westerburg was defeated at the Battle of Worringen in 1288, victorious citizens of Cologne demolished his fortress at Zons. Its stones were reused in the construction of Cologne’s city wall, ending this earlier phase of fortification.
The fourteenth-century customs castle
Archbishop Friedrich III von Saarwerden began building the present Burg Friedestrom in 1373 on the site of the destroyed fortress. The project followed the transfer of the Rhine toll from Neuss to Zons in 1372. The castle’s principal purpose was to protect and control this source of revenue, while its position also supported the expansion and defense of Cologne’s possessions along the Lower Rhine.
The castle was completed in 1377, and the fortification of Zons followed in 1388. Burg Friedestrom then formed part of the Electoral Cologne chain of fortresses that included Linn, Zülpich, Lechenich, Kempen, Hülchrath, and Uda. An official representing Electoral Cologne interests took up residence there. The customs castle reportedly produced about 5,000 gulden each year.
During the late fourteenth and early fifteenth centuries, a forward defensive wall was added on the west and north. The gate tower was widened, and a representative residential building was erected to its north. The north wing probably followed in the early sixteenth century. These changes connected the castle more closely with the wider defensive system of Zons.
Warfare, damage, and decline
Burg Friedestrom flourished during the fifteenth and sixteenth centuries. Its decline began gradually in the later sixteenth and early seventeenth centuries. During the Thirty Years’ War, the major European conflict fought from 1618 to 1648, Hessian Colonel Carl von Rabenhaupt besieged Zons and the castle in 1646. Heavy bombardment damaged the west wing so severely that it could no longer be used as a residence, although the attackers failed to capture the town and castle.
The electoral official consequently moved into the building later known as the Herrenhaus. The residential tower in the main castle was demolished between 1650 and the mid-eighteenth century, and the west wing of the inner castle was probably also removed during this period. The officials’ residence and the stable in the outer ward assumed functions formerly carried out in the main castle.
French forces under King Louis XIV captured Friedestrom during the War of the Grand Alliance, the conflict fought mainly from 1688 to 1697 between France and a coalition that included Brandenburg and the Dutch Republic. Combined Brandenburg and Dutch troops forced the French to withdraw in 1689 and occupied Zons and the castle until 1697. French troops seized the complex again in 1701 and devastated it.
Agricultural estate and modern restoration
French Revolutionary troops occupied Zons and the castle in 1794. The complex was then ecclesiastical property, but it was confiscated in 1802, when the inner castle had largely fallen into ruin. By the end of the eighteenth century at the latest, the complex had been converted into an agricultural estate. The French government auctioned it in 1803 to Matthias Melchior Aldenhoven, who adapted the buildings for agricultural use. A barn was erected on the site of the former west wing, and the north wing was altered.
Franz Joseph Aldenhoven later owned the property. In 1895, it belonged to Baron Daniel von Diergardt zu Mojawola, who leased it to the Aldenhoven family. The former Neuss district acquired the castle through a heritable building right in 1972 and converted it into a cultural center between 1972 and 1994. The work restored and repaired surviving buildings while also adding new structures.
Excavations by the Rhineland Office for Archaeological Monument Preservation in 1980 and 1981, and again from 1986 to 1988, preceded the construction of new buildings in the inner-castle courtyard. They revealed earlier remains, including the foundations of Romanesque churches, and their results are presented through displays and exhibits. Burg Friedestrom is protected as both an architectural monument and an archaeological monument.
The restored complex has continued to serve cultural and archival purposes. The modern west and south wings house the Neuss District Archive, which has been united with the Dormagen City Archive since 1 January 2007 under the name “Archive in the Neuss District.” The institution includes a specialist library devoted to regional and general cultural history. Since 1990, the same building sections have also housed the International Dialect Archive “Ludwig Soumagne,” a center for German-language dialect literature focused on the Rhineland. The archive alternates the biennial Friedestrom Prize with the Franz-Peter Kürten Award for services to Rhenish dialect.
The north wing of the upper castle has served as a central venue for cultural events since its restoration in 1989. An open-air stage occupies part of the eastern defensive passage, where an amateur theater group has performed mainly fairy-tale plays since 1935.
Remains
Burg Friedestrom is a partially preserved medieval water-castle complex that formerly stood directly on the Rhine before the river changed course. The almost square castle area occupies the southeast corner of Zons and covers approximately 11,000 square meters, about one-sixth of the old town. It consists of an inner castle, also called the upper castle, and a hook-shaped outer ward extending west and north. A defensive wall encloses the complex on all four sides, while its eastern and southern sections also form part of Zons’s town wall. The old town creates a second enclosure in front of the outer ward.
Water-filled moats formerly separated the castle from the town outside the surrounding wall and divided the inner castle from the outer ward. Groundwater lowering caused by nearby lignite open-pit mining left the moats dry, and some sections have been partly filled. The complex was built with columnar basalt, trachyte from the Drachenfels in the Siebengebirge, tuff, and Lower Rhine brick, using different masonry techniques in different building phases.
Outer defenses and entrance
A defensive passage runs along the entire south side of the castle. This space between lines of fortification averages 28 meters in width, including approximately 12 meters formerly occupied by the castle moat. The southern wall was once considerably higher than it is today. At the eastern corner stand the remains of a two-storey round tower that served as an icebreaker.
South Gate
A late-medieval double-gate system leads from the defensive passage into the outer ward. The outer gate, known as the South Gate, projects about 15 meters from the surrounding wall and has Gothic decorative forms. It was restored in 1983 and retains a rectangular plan with walls rising two storeys. The tall ground floor combines basalt, tuff, and brick, while the upper storey is built of brick.
The large gateway is framed in dressed trachyte and accompanied by a small pointed-arch pedestrian gate. Above the round-arched entrance, a barred niche with a trefoil-panel design contains a replica of a fifteenth-century Madonna statue. The original is kept in the district museum. Weathered heraldic shields flank the niche: one bears the cross of the Cologne archbishopric, while the other carries the double-headed eagle of the town’s founder as Count of Saarwerden.
Projecting polygonal corner turrets mark the upper-storey corners. They rest on pointed arches and contain machicolations, projecting openings through which objects could be dropped onto attackers. From the late fourteenth century, the South Gate allowed access to the castle independently of the town. A vaulted passage once connected it with the inner gate structure, and the walls of this gate lane survive.
Outer-ward buildings
Three buildings stand in a row along the north side of the outer ward and are now used by the Zons District Museum. The easternmost is the Herrenhaus, an elongated two-storey residence with a gabled roof, yellow plaster, and nine window bays fitted with red-and-white shutters. Its vaulted cellar retains two masonry domestic wells. The building took on its later name after the Electoral Cologne official moved there when the west wing was damaged during the Thirty Years’ War.
West of the Herrenhaus stands the former stable, a two-storey brick building with a gabled roof and windows framed in light dressed stone. Most of the present structure dates from its replacement in 1974. Farther west is a modern glass-and-steel hall, lower than the stable and completed in 1994. It is the newest building in the complex. Immediately west of it, the former town-side entrance in the outer-ward wall has been bricked up. The present town entrance, east of the Herrenhaus, was created after the Thirty Years’ War.
Juddeturm
The Juddeturm occupies the northwest corner of the outer ward. Built at the end of the fourteenth century, it is a six-storey round tower whose medieval name probably derives from the Cologne patrician Judde family, which may once have owned it. Its ground-floor walls are 2.10 meters thick. Machicolations and loopholes, narrow openings for weapons, emphasize its defensive purpose.
Basalt blocks and brick rise to a late Gothic frieze between the fifth and sixth storeys. The sixth storey has a continuous wall walk with brick walls carried on corbels and intervening pointed arches. Four arches are formed as openings for dropping objects or projectiles. Around 1600, a blunt conical roof was replaced by the present curved Baroque hood, which is crowned by an octagonal lantern, a slate roof, and a weather vane.
The ground floor contains a single octagonal room covered by a domed vault 3.30 meters in diameter. The windowless chamber formerly served as a prison, and serious criminals could be lowered through a floor hatch into a dungeon seven meters below. The first upper storey also contains an octagonal room, with external walls 1.60 meters thick. Fireplaces survive on the northeast wall and in the rooms on the second and third storeys, which served residential purposes.
A narrow spiral staircase with trachyte steps leads to the upper rooms. It occupies a slender five-sided stair turret on the east side and is reached through a narrow passage within the tower wall. A steep stone stairway from the courtyard rises along the inner face of the surrounding wall to this passage. Much of the outer ward is occupied by a castle park containing older lime, sycamore maple, and sweet chestnut trees, together with more recently planted ginkgo, European beech, and lime.
Inner castle
The inner castle was separated from the outer ward on the west and north by a moat 14 meters wide and 6.5 meters deep. Walls ran along both long sides. Its outer wall is built of basalt, while the inner wall consists of eighteen courses of trachyte blocks. The moat is now dry and partly filled. The four-storey gate tower on the west side, together with the surviving cores of the north and south wings, belongs to the Gothic main castle of the fourteenth century.
Gate tower
The west gate tower has a square plan measuring 8.40 meters on each side. Its ground floor is built of dressed trachyte blocks and contains a pointed-arch gate set within the recessed niche of a former drawbridge. Holes for the drawbridge chains remain visible. The first and second storeys are made of tuff with trachyte corner blocks, and the window surrounds use the same dressed stone. Cross-mullioned windows light the first upper storey.
Above the barrel-vaulted passage are two rooms placed one above the other. They served as guard chambers, and fireplace remains survive on the south wall. The chamber on the second storey connects with the defensive walk along the south side of the inner castle. A brick-built third upper storey projects as a wall walk with small corner turrets. It rests on a continuous late Gothic pointed-arch frieze of tuff, whose openings allowed objects or projectiles to be dropped onto attackers. The massive irregularly hipped roof replaced the deteriorated original in the 1970s.
West and north wings
The medieval basalt curtain wall meets the gate tower on the north and formerly served as the outer wall of the west wing. The present west wing is a modern building erected over the medieval wing’s foundations in 1990. Parts of the earlier structure survive in the cellar, including a six-meter-deep well that was most recently used as a latrine.
The north wing is the latest part of the historic fabric and the best preserved. This two-storey, unplastered brick building contains a single large hall on the ground floor above a late-medieval vaulted cellar. Restoration in 1989 exposed remnants of ornamented Gothic wall paintings in the hall.
South wing and Schlossturm
The southern part of the inner castle is occupied by a basalt-and-brick building. The section near the gate is original and includes a small corner turret at the southwest corner, while most of the structure, including its lean-to roof with dormers, is modern. Parts of a brick corbel frieze survive at the level of the former eaves cornice.
The massive round Schlossturm stands at the southeast corner of the south wing and therefore at the southeast corner of both the castle and the town. Its lower section is made of trachyte blocks with drafted margins, while the upper masonry is basalt. The tower is one of the four former corner towers of Zons’s town wall.
Courtyard churches
The three wings of the upper castle enclose a paved courtyard. Excavations in the 1980s uncovered the foundations of several Romanesque churches. Two ground plans are marked in the paving: red marks indicate a hall church dating from around the year 1000, while gray paving stones trace a second church built approximately two centuries later.
