Differdange Castle, now home to Miami University's Dolibois European Center, is a historical landmark in Luxembourg. Visiting the castle is generally free, though access to some areas may be restricted to students or during special events. The duration of a typical visit is around 1-2 hours. Due to its relatively small size and historical significance, it's suitable for both solo and guided visits. Accessibility may be limited in certain areas of the castle, so it's advisable to check in advance. Seasonal restrictions might apply to outdoor areas. Given its integration with the university, costs are primarily associated with transportation to Differdange.
