Kelemantia was probably a bridgehead for the larger fortress of Brigetio, across the river near Komárom. But it was still fairly big, at 172 metres (564 ft) square. The excavated and partly reconstructed fort, which is accessible via a rough lane from Iža, was the second to be built on the site. It contained barracks, stable blocks and a bathhouse and was surrounded by a stone wall two metres (6 ft 7 in) thick and up to five metres (16 ft) high. Parts of these structures are now visible and described by information boards in four languages, including English.
