Slot Zuylen Castle is situated on the river Vecht in the tiny village of Oud-Zuilen near Utrecht, The Netherlands. Whilst retaining many of its medieval castle-like features it was converted into a country mansion in the 18th century. Its most famous resident was Belle van Zuylen (Isabelle de Charrière), writer of fame and feminist avant la lettre. Slot Zuylen opened its doors to visitors 60 years ago and has meanwhile acquired museum status. The past is recalled to life through guided tours, garden walks, concerts and special events.
