Súľov Castle Súľov - Hradná

is alleged to have been founded by Hussites in the 15th century at the almost inaccessible summit of Roháč, as the castle hill was originally named. It is made up of two separate castles – upper and lower. Although the two castles stood almost next to each other, due to the large height differences a tunnel was carved through the rock to connect them. They became ruins after an earthquake in the nineteenth century
