The cave castle scooped in and erected on top of the Castle Hill of Sirok is a stunning medieval fortress in the region of the Tarna. It is interesting to note that huge ducts, stairs and rooms were formed in the belly of the rhyolitic tuff hill. The construction of the fortress of Sirok, comprising a lower and an upper castle, might have started in the 13th century, following the Mongol invasion, when the network of border fortresses became built with the aim of defending both royal and noble estates. The castle was renovated in 2012, and it is a popular tourist destination.
