Slot Purmersteyn | Grootgrondbezit in de Beemster

Where the square is now, an impressive castle was demolished in 1941: Slot Purmersteyn. During their visit to the newly drained Beemster in 1612, the Orange princes Maurits and Frederik Hendrik stayed in the castle. In 1608 the tenders were held at the castle by digging the ring canal and the construction of a surrounding dyke for the drainage of the Beemster.
