Blatnica castle was built in the 13th century to protect a major trade route running from Nitra to the north. Soon afterwards it became a royal castle but the kings lost their interest in the castle's development after a new route, through Mošovce and Martin was built. The new owners of Blatnica Castle, the Révay family (from 1540), were more generous and the castle was significantly extended in the second half of the 16th century. The last reconstruction dated from 1744. Since 1790 the castle has been abandoned and has turned into ruins.
The castle is built on typo low ridge of Plešovica which separates the Turiec Basin from the Greater Fatra Range. It is freely accessible from the village of Blatnica by a marked footpath. The castle remnants are hidden in a forest with limited views at the Gader Valley, which stretches underneath, and the opposite Tlstá Mountain.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
