The Water Gate, located southeast of the Great Basilica, was a major gateway at the bridging-point between the Vrina Plain and Butrint, opened during the construction of the Medieval wall circuit in the lower part of the city. It was a rectangular inlet into the wall circuit, defended by a tower. The first version of this gate was probably built in the 6th century AD, and it had an arched entrance with a second relieving arch above, decorated by the alternate use of tile and stone. It was later rebuild between the 13th and 14th century and reduced to a much smaller opening.
