Sulu is an island province of the Philippines located in the Autonomous Region in Muslim Mindanao (ARMM). Its capital is Jolo and occupies the middle group of islands of the Sulu Archipelago, between Basilan and Tawi-Tawi. It is home to the historical Sultanate of Sulu. Far-flung Sulu is the southernmost part of the Philippines, lying between the Sulu Sea on the north and the Celebes Sea on the south.
The glorious Sulu Sea is dotted with coral reefs, such as the pearl farm at Marungas Island, and provides some of the world’s best dive spots. Tubbataha Reef is its best known site, a 33,200-hectare underwater splendor drawing divers from all over the world with its marvelous marine wilderness and special ecosystem.
The provincial capital is Jolo. Its walled city is the smallest in the world, with its historic brick walls that lay proof to the city’s historic and continuous strife. At the entrance of the city are four gates that were used as watch towers and several mounds that were the burial grounds of Spanish and American soldiers who died in the hands of the Muslim warriors. Another attraction of the city is the Provincial Capitol with its moorish-inspired architectural design.
The province nurtures a harmonious coexistence of the two most dominant religions in the Philippines, Catholicism and Islam. There are Muslim mosques situated in each barangay, most notable being the Tulay Mosque. The existing churches of Christian faith in the province are the Jolo Parish Church, Sacred Heart of Jesus Chapel, and Jolo Evangelical Church. The province consists of over 400 scattered and almost isolated islands, stretching from the tip of Zamboanga southwestward towards Borneo. It forms one of the three connections of the Philipines with Borneo.
