 However, the largest and most visible evidence of the village's early history is the "G'Schlößl," a structure consisting of three concentric rings of walls and ditches, built in the 13th century out of the ruins of the Roman watchtower, and used as a dike to stay protected against flooding of the Leitha River.The city later belonged to the Austro-Hungarian Empire, and because of its policy of Magyarization, the name of the settlement was changed to Lajtapordány.After the end of World War I, the city was transferred to the newly split country of Austria.
