The name of the Modrý Kameň town was first mentioned as Keykkw ('Blue rock') in 1290. Ruins of the Modrý Kameň castle stand on a rock pinnacle above the town. The castle was built in the second half of the 13th century by the ancestors of the Balassa noble family. They had to recapture the castle from sons of Casimir of the Hunt-Poznan clan by a siege in 1290. The castle was captured by Ottoman troops in 1576, because its guard fled when they heard the approaching Ottomans.
The castle was given up and subsequently destroyed by Ottoman troops in 1593. It was restored between 1609 and 1612 by Sigismund Balassa. The castle was ravaged many times during the 17th century, so it became ruined and abandoned. The Balassa family built a new Baroque mansion house on the side of castle hill in the early 18th century; stones of the former castle were used in the mansion building operations. The last member of the Balassa noble family died in 1899. After the demise of the Balassa family, the Almásy noble family became the proprietors of castle Modrý Kameň. They sold the demesne to the Czechoslovakian state in 1923.
Now the manor house contains the Museum of Puppets and Toys, the only one of its kind in Slovakia. Visitors can see a permanent exhibition 'From the Life of Dwarfs'. The historical exhibition of dentist technology of the Slovak Chamber of Dentist installed here is unique in central Europe. Apart from exhibitions, several interestingevents and festivals are organized at the Castle.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
