This is what the baukunst-nrw editorial team writes:
"Buldern Castle, which is located in the district of the same name in the city of Dülmen, is a classicist castle complex that is now used as a boarding school. The complex was originally owned by the Lords of Buldern until, after numerous changes of ownership, it was taken over by the family in the 18th century von Romberg. This had the previous building, which was probably built at the beginning of the 17th century, extensively renovated. In 1945 the complex was already used as a student dormitory and in 1958 a boarding school for boys and girls was finally founded in the castle.
The complex consists of the classicist manor house, some farm buildings and a landscape garden. The manor house, which dates from 1838, is a plastered building with a rectangular floor plan, which ends on its front side in the north with two tower-like pavilions at the corners. The north side is also characterized by a gabled central projection with an arbor supported by pillars. To the south, there is a brick wing attached to the manor house, which is still part of the previous building from the 17th century. The outer bailey in the southeast has also been preserved mainly from the 17th century. The gatehouse is marked with the year 1678.
The 19th century farm buildings include two barns and a brick watermill. Inside the manor house, the wall and ceiling paneling from the 19th century and a fireplace from the 17th century have been preserved in the dining room.
The landscape garden was probably created together with the manor house in the 19th century and is characterized by large water areas and some preserved structures. The park was redesigned between 1910 and 1920."
