The National Police Memorial in India commemorates the 34,844 police personnel from all of the central and state police forces in India who have died in the line of duty since the nation's Independence in 1947. Located in New Delhi's Chanakyapuri area, the 6.12 acres (2.48 hectares) memorial consists of a 30-foot (9.1-metre) tall and 238-tonne (234-long-ton; 262-short-ton) heavy black granite central sculpture, a museum and a 'Wall of Valour' bearing the names of all 34,844 police personnel who have died in the line of duty. The underground museum is the first police museum of its kind in India, and showcases over 2000 years of policing in the region, since the time of Kautilya's system of law and order in 310 BCE.
