Trsat Castle (Croatian: Gradina Trsat) is a castle in Trsat, Croatia. It is thought that the castle lies at the exact spot of an ancient Illyrian and Roman fortress. The Croatian noble Vuk Krsto Frankopan is buried in one of the churches. The Trsat castle was completely reconstructed and renovated in the 19th century when the mausoleum of the military commander Laval Nugent was built in its interior. The courtyard of the castle has now been turned into a restaurant and many tourists visit the place during the summer months.
