The detached mansion (once inhabited by gentleman farmer, Mayor Hendrik Scheringa Az) and Westerhem stolp farm were built in 1877. In 1965 the municipality of Beemster bought the mover 17 ha large cattle farm for the purposes of providing homes and emergency classrooms for the secondary school. A few years ago, the farm was transferred to the Beemster Historical Society. After a thorough renovation in the spring of 2000, the stolp was set up as an agricultural museum and opened to the public on 1st June.
