The Castle Museum in Ostrzyhom is a branch of the Hungarian National Museum and arranges exhibitions on the territory of the Ostrzyhom fortress. This building was inscribed on the UNESCO World Heritage List, and the most important objects inside the castle include the fresco attributed to Botticelli, depicting Temperance. This fresco decorates the wall of the room known as the workshop of Jan Vitéz.
Seven halls and a chapel are available to visitors within the castle. Four permanent exhibitions of the Museum are presented in these rooms. They concern the history of the castle, Ostrzyhom and Hungary. Here we will also see Hungarian arms collections and specimens of Hungarian coinage. In the chapel representing the late Romanesque style you can admire the remains of 12th-century frescoes.
The castle in Ostrzyhom was built in the 10th century. The construction began with the Hungarian prince Gejza and was continued by his son, King Stefan. In the eleventh century, this castle was of particular importance, and Ostrzyhom was at the time the center of the Hungarian state.
