It stands in the walls that run from the Old Bisagra Gate to San Martin Bridge. The gate located at the place where a very large water course runs out of the city during rains, and must therefore date from the earliest times. Part of the original structure is still conserved in the outer part of the gate, in the form of the opening with a square tower on either sides. Two large Arab memorial stones can be seen in the base of these towers, taken from the nearby cemetery. The original inscription can still be seen, on face of one of them.
