Zagreb, capital of Croatia
The ruins of Samobor Castle (Stari grad Samobor), originally built between 1260 and 1264 by supporters of Czech King Ottokar II of Bohemia. In the third decade of the 16th century, the core was reshaped by a gradual expansion towards the north. The castle was upgraded and reconstructed throughout the 17th and 18th centuries but fell into ruin afterwards.
