Šášov castle is located at the edge of the Štiavnické mountains on a steep rock that overlooks the valley formed by the river Hron, near Žiar nad Hronom, the TASR newswire reported.
Historical documents suggest it was built in the 13th century.
The association to save the castle is attempting to preserve the remains of this medieval fortification and renew parts of it.
The castle is accessible by a short but steep walk that takes about 15 minutes.
