Troskovice is known for the ruins of the
Trosky Castle. The castle was built on a unique rock formation, formed by two tower-like peaks called Panna ('virgin') and Baba ('old woman'). During the
Thirty Years' War, the castle was conquered by the
Swedish army and burned down, and it has been a ruin ever since. For its value, the castle is protected as a
national cultural monument. The castle is among the most visited tourist destinations of the Liberec Region. Next to the Nebákov pond is a Baroque water mill, protected as a cultural monument. It was rebuilt into its current form in 1743. ==In popular culture==
