Popta Slot is located in the small village of Marssum just outside of Leeuwarden. The building is a 18th century manor house that was once the home of Dr Popta. Popta was an affluent lawyer, and he spent a lot of his fortune building the nearby Popta Gasthuis – an almshouse for elderly ladies and widows in need. The manor has been preserved with 17th and 18th century period furnishings, and now serves as a museum.
