While loosely modelled after a Transylvanian fortress of the same name, the building is not really a castle at all. It is a full-scale model built for Hungary's 1896 millennial celebrations. The structure has three distinct wings, one Gothic, one Romanesque and one Baroque, making it quite a bizarre sight when seen from a distance. But sneak up closer and its magic will be revealed: thanks to the moat, the trees and the carefully laid footpaths, you can usually only see one section at a time. The attention to detail (all copied from real sites around the country) has been painstaking, so it's like seeing three extraordinarily pretty castles rolled into one. The structure was supposed to be only a temporary one, but Budapest's people liked it so much that it was rebuilt to last. It is on an island in the middle of the park's lake.
