Protohistory

Carl Guthe, director of the University of Michigan Anthropological Museum, during his 1923-25 collecting trip and explorations of archaeological sites in the Philippines,^[5] conducted an archeological dig in a cave site on Tulang. Located on the southeastern coast of the island, the cave measures about 3.7 by 2.7 metres (12 by 9 feet). Guthe reported it to contain bone fragments and teeth of about 60 individuals. Associated grave goods included earthenware pottery, shell bracelets, bronze and iron artefacts (iron tang, bronze chisel, iron blade), glass and stone beads, hammerstone and pestle. Filed teeth were also recovered from this site.^{[lower-alpha 1]}

21st century

Just before Typhoon Yolanda struck in November 2013, the mayor of San Francisco ordered the evacuation of all the residents (approximately 1,000) to the main island. This was credited with saving their lives as all houses on the island (about 500) were completely destroyed.^[6]

Pacijan (Pajican) Island

Pacijan Island is about 14.75 kilometres (9.17 mi) long and 8.5 kilometres (5.3 mi) wide. A 1,400-metre (1,530 yd) causeway crosses the mangrove swamp to connect Pacijan and Poro islands. It was constructed during the Spanish era, to bridge the islands for easier trading and attending services in Poro church.^{[citation needed]}

Tulang

Tulang island (known locally as Tulang Diot) is a five-minute boat ride from Tulang Dako on the main island of Pacijan. Both Tulang Diot and Tulang Dako are part of Esperanza barangay. The islet is almost entirely covered with coconut palms and measures about 1.6 by 0.6 kilometres (1.0 by 0.4 mi): the residential area is confined to a small triangle at the southern end. Total area is less than 1 km² (0.39 sq mi) or 40 ha (100 acres), of which only 3.5 ha (8.6 acres) (8.8%) is inhabited.^{[citation needed]}

Barangays

San Francisco is politically subdivided into 15 barangays. Each barangay consists of puroks and some have sitios.
