Blue Stone Castle, or Hrad Modrý Kameň, serves as the seat of the Museum of Puppet Culture and Toys, located within the surviving 18th-century Baroque manor house. The site overlooks the remains of a 13th-century Gothic castle which fell into ruin following the Ottoman-Habsburg wars. The museum houses one of Central Europe's most significant collections of historical puppets, marionettes, and antique toys. Visitors explore both the residential Baroque mansion and the adjacent medieval fortifications. The complex is situated on a rocky ridge, utilizing the natural terrain for its strategic defensive layout. Excavations and partial restorations have stabilized the older castle walls to allow for public access. The site highlights the history of the Balassa noble family, who held the property for centuries. It remains a regional center for theatrical arts and heritage conservation.
