Triforium is a 60-foot high, concrete public art sculpture mounted with 1,494 Venetian glass prisms, light bulbs, and an internal 79-bell carillon located at Fletcher Bowron Square in the Los Angeles Mall at Temple and Main streets in the Civic Center district of Downtown Los Angeles.

The Los Angeles Mall is a small shopping center and series of plazas at the Los Angeles Civic Center, between Main and Los Angeles Streets on the north and south sides of Temple Street, connected by both a pedestrian bridge and a tunnel. It features Joseph Young's sculpture Triforium, a colorful sculpture unveiled in 1975, which has 1,500 blown-glass prisms synchronized to an electronic glass bell carillon. The mall opened in 1974 and includes a four-level parking garage with 2,400 spaces. It stands on the site of what once was some of the oldest commercial blocks in the city that was demolished in the 1940s and 1950s.
