At 21:22 pm on 4 August 1977, Vrancea earthquake killed 1,424 people and wounded more than 7,500 in Bucharest. The earthquake particularly affected the capital´s multi-storey buildings, mostly apartment buildings, leaving over 35,000 families without shelter.
After the 1977 earthquake, dictator Nicolae Ceaușescu decided to demolish about one-fifth of old Bucharest and relocate 40,000 people to build the People’s House (Casa Poporului) on top of the Spirea’s hill in the centre of the city.
Constructed over a period of 13 years (1984–1997) the Palace is the world’s heaviest building, the second largest building in the world in terms of size and the third largest in terms of volume.
