Prime Minister dedicated National Police Memorial to the nation on October 21 which is observed as 'Police Commemoration Day' every year in memory of the policemen killed at Hot Springs in Ladakh by the Chinese troops in 1959. The memorial has been built in recognition of the supreme sacrifice made by the police since independence. The central sculpture of the National Police Memorial is a 30-feet monolith made of a single piece of granite, weighing 238 tonnes. Its weight and colour symbolise the gravitas and solemnity of the supreme sacrifice. The memorial represents all State/UT police forces and central police organisations of the country. The memorial is erected in Delhi's Chanakyapuri and the Wall of Valour has the names of all 34,844 martyrs engraved on granite. The memorial also has the country's first National Police Museum which captures history, artefacts uniform and gear of central and state police forces.
