Vibyholm Castle () is a manor house at ÃÂ rdala, Flen Municipality, Sweden. The main building is located on an island in Lake BÃÂ¥ven.
Vibyholm was built between 1622 and 1630 in Dutch High Renaissance style under design by Dutch architect Caspar van Panten (1585-1630). Restoration was made in 1798 following drawings by Swedish architect Carl Christoffer Gjörwell (1766-1837). In the middle of the 19th century, restoration to the house was undertaken under the direction of Swedish architect Lars Jacob von Röök (1778-1867).
