The Roman fort of “Kelemantia” lies directly on the left bank of the Danube in the limits of the modern village of Iža (Komárno district, Slovakia). It is situated only 4 kilometres east of the confluence of the rivers Váh and Danube. As a bridgehead of the legionary fortress in Brigetio once it was a segment of the fortification chain system of limes romanus. The limes was a frontier protecting the Roman Empire. The area where the fort used to be in Roman period, today terrain only slightly rises as a square shaped plateau from the surrounding plane. Its name is Leányvár (Virgins castle).
