The Gallarda Gate, at the base of the rectangular or Gothic portal-tower, was the entrance to Castelló’s fortified enclosure from the upper side. It is above the mill irrigation channel which makes use of the ancient moat in the town’s best conserved section of the wall. It follows the high-medieval line and was renovarted in the XIII-XIV centuries. One can see this fortified section running up to the apse of the cathedral from outside the wall.
