Trenčín Castle is a hilltop medieval fortress overlooking the town of Trenčín in western Slovakia. Its origins reach back to the early Middle Ages and it is one of Slovakia’s most extensive castle complexes.

The complex includes a sequence of defensive walls, towers, and residential buildings arranged on a rocky spur, with panoramic views over the Váh River valley. Visitors commonly explore the castle courtyard, exhibition spaces, and the elevated battlements.
