Note 11 — Chapter I · Geographical Description of the Sulu Archipelago1

The town wall had five gates, two of which lay on the northwest or sea front, one at the foot of the pier, and the other close to it. Through the latter gate cargo was admitted from small boats, which can always come up to this point at high water. The three other gates lay on the land side, one at the south end of the town toward Tulay, another at the opposite extremity facing Busbus, and a third one at the southern end of Calle11 Buyon, directly facing San Remondo. This last is the only gate of the three kept open at present and is the only entrance into the town from the land side. A tower called Torre de la Farola surmounts the gate. Near the Busbus gate and forming the northeast angle of the town was the fort or redoubt termed Alfonso XII. It was built on a prominent eminence and commanded an extensive view of the bay, the town, and the surrounding country.
