This royal castle from the 13th century became the centre of the castle estate of Topoľčany. During the Rákoczis rebellion it was severely damaged by the Imperial troops and although it was later reconstructed, it fell into decay.
Today its main tower, built in a Romantic style, with well preserved fortifications dominates in the horizon. The views from the platform below the Castle are unique. Above all the eastern side where almost the whole upper part of the region Nitra, mountain range Tribeč with its dominant Zobor and mountains Strážovské vrchy in the north-east, as well as the side ridge of mountain range Považský Inovec are captivating.
