chartered city, central Luzon, Philippines. The city lies on the principal north-south highway and railway lines 50 miles (82 km) north of Manila. Angeles is the site of Angeles University (founded 1962), a Roman Catholic seminary, and several other colleges. Once known as the “city of the dollar,” Angeles had an economy fueled by its proximity to the American-run Clark Air Base, which was responsible for the rapid growth of the city by providing substantial employment, housing, and business opportunities. With the eruption of Mount Pinatubo (Pinatubo, Mount) in 1991 and the subsequent decision by the U.S. government to abandon the ash-covered air base, the city's future became uncertain. Inc. city, 1963. Pop. (2000) 263,971.
