Zvolen Castle ranks amongst the National Cultural Sites of Slovakia.
It was built as a Gothic hunting chateau from 1370 - 1382 for the needs of the Ungrian king, Louis I of Anjou. Later, it became the property of Ungrian queens, aristocratic families of Thurzo and Esterhazy, from the end of the 15th Century it became the seat of the Zvolen Mayor and Captain of Central Slovakia Mining Towns. Zvolen Castle was an important part of the anti-Turkish protective line. Therefore, the change in its function and appearance corresponded with this. From 1491 - 1510, the castle was fortified with four round towers in the corners and after 1548, Renaissance rebuilding of the castle palace took place, finished with attics in the spirit of Italian quatrocento. An outer fortification was built and partial building changes took place in the 17th and 18th Centuries, when its significance declined.
After several years of makeshift use, the castle became the workplace of the Slovak National Gallery.
