Built on the site of a hill variously known as Spirii Hill, Uranus Hill, or Arsenal Hill, which was largely razed for this megaproject in 1980, the building anchors the west end of Bulevardul Unirii and Centrul Civic.Constructing the Palace and Centrul Civic required demolishing much of Bucharest’s historic district, including 19 Orthodox Christian churches, six Jewish synagogues, three Protestant churches (plus eight relocated churches), and 30,000 residences. Over 700 architects and three shifts of 20.000 workers labored on it 24 hours a day for five years.In 1980, when lit, the building consumed a day electricity supply for the whole of Bucharest in 4 hours. The building is constructed almost entirely of materials of Romanian origin. The movie Amen by Costa Gavaras was filmed here in 2002 meant to respresent the Vatican. The Top Gear team has filmed in the underground tunnels and garages in 2009.In 2008, the Palace hosted the 20th NATO summit.
