Soon thereafter a castle was raised in Falsterbo. In 1311 the castle was destroyed by the Hanseatic League (specifically the trade towns of Rostock, Wismar and Greifswald) in the war between these and the Danish king Erik Menved. After the war the king raised a new and larger castle in 1318 called Falsterbohus. The old castle in Skanör thus lost its importance thereafter. Olav IV of Norway, son of queen Margaret I of Denmark, died in 1387 in Falsterbohus.
