Pershing Square is a public park in downtown Los Angeles. The park is exactly one square block in size, bounded by 5th Street to the north, 6th Street to the south, Hill Street to the east, and Olive Street to the west. It sits on top of a large underground parking garage. In 1992, the park was closed for a major $14.5 million redesign and renovation by architect Ricardo Legorreta of Mexico, and landscape architect Laurie Olin of the U.S. The new park opened in 1994 with a 10-story purple bell tower, fountains, numerous public artworks including a walkway representing an earthquake fault line designed and executed by artist Barbara McCarren, a concert stage, a seasonal ice rink, and small plazas with seating. It is now predominantly paved expanses, with small areas of trees in raised planters.
