Liptovský Hrádok Castle, also called Hrádok or Nový Hrad (New Castle), is the remains of a water castle, unique in Slovakia.
It is located on a small limestone rock near the Belá River, in the northern part of the town of Liptovský Hrádok. The lake in front is the remains of former water moat that once surrounded the castle.
The first written reference to the castle is from 1341. It is connected with a manor house, thanks to its unique construction.
