Rolduc is the name of a medieval abbey in Kerkrade, the Netherlands, which is now a Roman Catholic seminary and an affiliated conferencing center. The abbey is a rijksmonument. It is part of the Top 100 Dutch heritage sites, established in 1990 by the Department for Conservation.
In 1104, a young priest by the name of Ailbertus of Antoing founded an Augustinian abbey in the Land of Rode, near the river Wurm. The abbey was called Kloosterrade, which later became 's-Hertogenrade (in French: Rode-le-Duc or Rolduc), after the ducal castle that was built across the Wurm. Ailbertus died in 1111 and his bones were later interred in the crypt. In 1136 the land of Rode, including the abbey, fell into the hands of the Duchy of Limburg. Kloosterrade was considered to be their family church. Several dukes of Limburg are buried at Rolduc, such as Walram III, whose cenotaph can be found in the nave of the church. During the 12th century and 13th century the abbey flourished. Several other communities were founded by Kloosterrade. In 1250 the abbey owned more than 3,000 hectares of land.
During the 14th, 15th and 16th centuries times were harder for the abbey in both spiritual and material terms. The buildings were heavily damaged during the Eighty Years War. Materialistically, the abbey began to prosper again in the late 17th century when revenue was generated from the exploitation of coal mines. In around 1775, Rolduc employed 350 mineworkers.
The abbey was dissolved by the French in 1796 and the buildings stood empty for 35 years. In 1815, when the Kingdom of the Netherlands was formed (see Vienna Congress), the border was drawn through the ancient land of Rode, separating the abbey from the castle. The eastern part (including the castle) became Prussian Herzogenrath and the western part (including the abbey) became part of the Dutch municipality of Kerkrade.
