The Sultan's palace, termed istana, his kuta (fort) and stockades were built along the lower left bank of the stream Bawang; hence the name Rio del Sultan. On the right bank lay the houses and stockades of the other datus of high rank. Two bridges connected one side of the stream with the other. On the outskirts of the town lay various kuta belonging to subordinate datus, which defended the approaches to the town. The most famous of these kuta was Daniel's Fort, the best stronghold of Sulu. On the site of this fort was built in 1878 the fort or redoubt of Alfonso XII, which was lately replaced by the present headquarters building of the military post of Jolo. Another strong fort was built at the foot of the hills just above the head of the delta above described; it defended the inland approach to the town. This was Panglima Arabi's kuta, on the site of which Fort Asturias was erected. Another kuta was located on Point Baylam. The principal part of the town was formerly built over the shoal and beach at the head of the bay. Extensive rows of buildings stretched out into the roadstead and in front of the buildings now occupied as the clubhouse and military hospital. The present "Chinese pier" is constructed on the same plan. This extensive row of houses and shops begins at the lower point of the Tulay delta and stretches straight out into the sea. The bay is very shallow here and appears to be fairly well protected from severe storms. A variety of fish called tulay, after which the Moro town of Tulay is named, is caught in the bay. A swamp bounds the town on the south and west, affording it considerable protection from assault. However, it is open to attack from the sea and from the east. The land on the east is high and affords the only desirable site for residences. Here the strongest forts and defenses were erected. The Spaniards built the central part of Jolo first. They raised it considerably above sea level by extensive fillings, and surrounded it by a loop-holed wall, 8 feet high and 1 1/2 feet thick, for protection from Moro assaults. The new town was beautifully laid out with broad, clean streets lined with double rows of arbol de fuego (fire trees), ylang-ylang, [11] acacia, and other varieties of trees, some of which are large and magnificent. Three parks, each one block in size, added considerable picturesqueness to the place. Substantial quarters were built for the officers, all houses were painted white or whitewashed, and none of them had the nipa roofs so common in the Archipelago. Business places, storehouses, a large market place, a church, a theater, two schoolhouses, and a hospital were erected and a public water supply provided. A stone pier was built extending 120 meters into the sea, and provided with a light-house at its outer end.
