The Seismolen is a historic corn mill located on Seisbolweg in the town of Middelberg. The mill was built in 1728. The Seismolen was idle for much of the 20th century, some restoration attempts were made, but were not completed because of lack of funding. The mill was dismantled in 1998 for safety reasons, and re-built the following year in a project funded by the Middelberg County. The mill was re-opened by Professor A. Asselbergs of the National Heritage Office in April 2001.
