History
Landsfort Herle is a medieval fortress church in Heerlen, Netherlands, whose origins lie in an eleventh-century residential tower and whose site became the historic core of the city. The church and its surrounding walls combined religious and defensive functions, while the rounded enclosure shaped the street pattern around the present Pancratiusplein.
Lordship and early development
In the eleventh century, the allodial estate of Heerlen, meaning land held as free property rather than as a feudal fief, belonged to Udo, son of Count Riquinus and Countess Mathilde. As bishop of Toul, Udo donated his possessions in Heerlen to the Church of Toul. His family probably annulled that donation, since his nephew Theoderich still owned the estate in 1121. Theoderich was succeeded by his grandson, Theoderich II, Count of Are, after which Heerlen became part of the possessions of the Counts of Are-Hochstaden.
The oldest surviving element of the stronghold was an eleventh-century residential tower, later known as the Schelmentoren. In the early twelfth century, an oval enclosure was formed around it by an earthen rampart. A small church, the predecessor of the present Pancratiuskerk, stood at the centre and was enlarged during the third quarter of the twelfth century. The rampart was replaced relatively soon by a sandstone and Kunrader stone curtain wall, an enclosing defensive wall linking the fortress gateways and towers.
Conflict and reconstruction
The military stronghold was first mentioned in 1225 as castrum de Herle. In 1239, the Duke of Brabant destroyed it during his conflict with Koenraad of Hochstaden, Archbishop of Cologne, over the appointment of the Bishop of Liège. Heerlen lay within the Brabant sphere of influence, but its lord, Dirk of Are-Hochstaden, had opposed the duke because of his kinship with Koenraad.
After peace was concluded at Roermond in 1244, Dirk received permission from the Duke of Brabant to rebuild the fortress. Dirk died in 1246, and his uncle Frederik inherited his possessions. Frederik then donated them, including Landsfort Herle, to the Archbishop of Cologne, who administered them through the Manhuis feudal office.
The Duke of Brabant successfully besieged Landsfort Herle in 1318. A document from that year called Heerlen an oppidum, a term indicating development toward an urban settlement. Heerlen did not later receive formal town rights after the Counts of Are-Hochstaden ceased to own it, but the fortress continued to serve as a military centre.
A fortified freedom
Heerlen held the status of a freedom, a settlement with particular legal and economic privileges. The territorial lord retained one fief, while residents held the remaining land and were exempt from certain taxes and labour obligations. Surrounding inhabitants possessed refugierecht, the right to seek safety inside the fortress walls during danger. A schepenbank, or local court administered by aldermen, also operated within the settlement.
Around 1400, Heerlen came under the authority of the Burgundian dukes, rulers of a state that expanded across parts of the Low Countries during the late medieval period. The fortress remained involved in warfare. A Guelders army besieged it in 1543, and fighting took place there repeatedly between 1588 and 1594.
From the first half of the sixteenth century, the residential tower served as a prison. Its later name, Schelmentoren, became associated with that function, which continued until 1879. The tower and the fortress church therefore retained practical roles long after the stronghold’s medieval formation.
Dismantling and archaeological recovery
After Heerlen’s military importance declined, the 1661 Partition Treaty transferred it to the Dutch Republic, the early-modern state formed by the northern Netherlands after their revolt against Spanish rule. In 1670, the schout and aldermen asked the States-General to restore the decayed fortress. The Republic considered it militarily unimportant and repaired only the entrance gates.
The fortress was progressively dismantled. Parts of the walls were removed during the eighteenth century. The southwestern Akerpoort, also called Trichter Poort, lost its function, and the walls around it were demolished in 1760 and again between 1778 and 1788. Part of the moat along Pancratiusstraat had already been filled during the late seventeenth century and turned into kitchen gardens before being built over in the eighteenth century.
By 1822, two sections of the moat remained, Bongerdpoel on the north side and Kerkgraaf on the south side. Both were filled in during 1899. Twentieth-century urban development removed further wall sections: the parsonage and adjoining wall were blown up with dynamite in 1902, another section disappeared during construction at Emmaplein, and the wall south of the church choir was demolished around 1919. Further houses and walling were removed for the Schunck department store in 1933. Urban clearance begun in 1967 removed another wall remnant for parking spaces, while the last original above-ground section near the parsonage was retained.
Archaeological investigations during building works and urban-renewal projects recovered fortress remains and helped establish the course of its walls. In 2006, a short section was rebuilt on Pancratiusplein with original stones. The Schelmentoren, a surviving wall section, and Pancratiuskerk are registered as national monuments.
The fortress also remained part of local tradition. Until the early twentieth century, Kermismaandag included a reenactment of the storming of Heerlen fortress. The event lost appeal as the moat and walls were dismantled, and the “storming” was prohibited after an incident in 1906. One reenactment took place in the 1970s, and the tradition was revived in 2017 through the obstacle race HeerlenStormt.
Remains
Landsfort Herle occupied an oval enclosure measuring approximately 110 by 93 metres. A moat about 12 metres wide and more than 5 metres deep surrounded the rampart and was supplied by the Caumerbeek. The earthen defence was replaced during the twelfth century by a curtain wall of sandstone and Kunrader stone. This wall consisted of two parallel walls set about 4 to 5 metres apart, with the residential tower incorporated into the circuit.
Enclosure and gateways
Wall circuit and entrances
Three gateways were set into the enclosure. Aeckerpoort, also known as Trichter Poort, stood in the northeast. Kerkhofspoort, also called Veemarktspoort, occupied the southwest, while a third gate stood beside the Manhuis on the southeast side. These entrances were reinforced openings in the curtain wall rather than separate gate buildings.
A rectangular system of waterways surrounded the fortress. It has been proposed that these channels formed a second moat with an accompanying earthen defensive bank, but the more likely interpretation is that they were drainage ditches serving meadows and fields. The fortress outline remains recognizable in Heerlen’s street pattern, including Pancratiusplein. The wall course is marked in the paving, archaeological work has recovered sections of the wall, and a bronze model of Landsfort Herle stands on the square.
Moat and settlement
Settlement extended both within and beyond the fortified enclosure. Twenty-five houses stood inside the walls in the seventeenth century. Outside the enclosure were houses, grain-storage buildings, and workshops, with habitation in this outer area extending back to the tenth century.
Church and towers
Pancratiuskerk
Pancratiuskerk occupies the centre of the former enclosure and developed from the small church established there before the present building. It was enlarged several times, including during the third quarter of the twelfth century. The church tower contains loopholes, and the possibility of attaching a wooden gallery around the tower suggests that the building may also have had a defensive function.
The church was enclosed by a walled cemetery. Small rooms were built into the rafters to shelter Heerlen’s inhabitants during hostilities. These rooms were destroyed when a bomb, believed to have been German, struck the church on New Year’s Eve 1944–1945.
Schelmentoren
The Schelmentoren is the surviving residential tower from the earliest phase of Landsfort Herle. It was incorporated into the later curtain wall and subsequently served as a prison from the first half of the sixteenth century until 1879. Together with the church belfry, it formed one of the fortress’s two towers. Both towers are described as having walls approximately 2 metres thick.
The surviving physical remains therefore consist of Pancratiuskerk, the Schelmentoren, part of the original curtain wall, archaeological wall traces, and the reconstructed section on Pancratiusplein, which uses original material. A reconstruction of the fortress model was made from a map dating to 1787, discovered during extensive restoration work at Pancratiuskerk in the 1960s.
