The castle that rules Brkini and the Reka Valley was built in 1213. Over the following centuries, it changed many owners, among them the Walseeis, Hallers, Habsburgs and the Porcia Dukes. The compact two-story residential part of the castle has a Romanesque nucleus and a small yard protected by walls. The inner yard was decorated with Renaissance arcades and the entire structure is protected with exterior Renaissance walls and round towers. A walking trail and a couple of bike trails lead past this exceptional place.
