Bunker Hill, Los Angeles is a neighborhood of Los Angeles, California that is located near the city center. Bunker Hill was originally a residential suburb, but increased urban growth following World War I led to the area becoming the most crowded and urban neighborhood of Los Angeles. When the Pasadena Freeway was built by World War II, many residents left Bunker Hill, which became a home of impoverished pensioners. In 1955, city commissioners began a slum clearance project in Bunker Hill, and they sought to create a modern and sophisticated image by creating large skyscrapers during the 1980s. Modern plazas and buildings replaced old slum areas, giving Bunker Hill its distinctive appearance.
