It is considered as one of the most beautiful castles in all of Europe, and for that reason alone it deserves a visit. It was originally commissioned as a summer residence during the reign of King Carol I of Romania. The castle can be reached by a quick 20-minute walk from the village of Sinaia, through an incredibly wondrous and lush forest. Once you’re at the castle grounds, you’ll be delighted by the Neo-Renaissance architecture, pristine courtyards and amazing gothic sculptures that adorn the castle’s walls. The castle is closed on Mondays to visitors and also during the month of November. Visitors will have to join a guided tour to get inside the castle and can choose from tours ranging from one floor to all three.
