Mactan is an island located a few kilometres from Cebu Island in the Philippines. The island is part of Cebu Province and it is divided into Lapu-Lapu City and the municipality of Cordova. The island is connected to Cebu by the two bridges one of which is the Marcelo Fernan Bridge and the Mactan-Mandaue Bridge. The Mactan-Cebu International Airport, the country's second busiest airport is located on Mactan island. The island was a Muslim settlement before it was colonized by Spain in the 16th century. Portuguese explorer Ferdinand Magellan arrived on the island in 1521 and became involved in tribal warfare among the tribal groups, only to be killed in battle by the warriors of Datu Lapu-Lapu, one of the chieftains in the island. By 1730, Augustinian friars established the town of Opon, that was later renamed as the city of Lapu-Lapu by means of the Republic Act 3134, signed by Pres. Carlos P. Garcia on June 17, 1961.
