The tower is the southernmost castle lookout tower in the Czech Republic. Part of the complex is a museum mapping the history of the place from the Bronze Age to the present day and a tavern named after the important Rožmberk burgrave Čap of Radonice.

A large and gate tower with an entrance, a moat carved in the rock and the ground floor of the palace have been partially preserved. The visitor will especially appreciate the full symbiosis of nature and architecture. There is an information panel in front of the forecourt.

At the turn of the 14th and 15th centuries, the castle surroundings became a place of rampage of a group of captors and opovědníci, including Matěj Vůdce and Jan Žižka of Trocnov. The latter, among others, killed an unknown member of the Rosenberg retinue here. The castle disappeared in 1448.

Pořešín Castle is currently a modified ruin with a tour route equipped with picture panels showing its original appearance. The site includes a historic forge, kitchen, pottery and museum. During the season, a tavern with complete sanitary facilities is open.
