The Mumbai Heritage Conservation Committee (MHCC), established in 1995, formulates special regulations and by-laws to assist in the conservation of the city's heritage structures. Mumbai has three UNESCO World Heritage Sites, the Chhatrapati Shivaji Terminus, the Elephanta Caves and the Victorian and Art Deco Ensemble.[25] In the south of Mumbai, there are colonial-era buildings and Soviet-style offices.[26] In the east are factories and some slums.
