Located on Spirii Hill in central Bucharest, the Palace is the world's largest civilian building with an administrative function and the second largest building in the world after the Pentagon in the United States.

The Palace was designed by architect Anca Petrescu when she was only 28 years old. It was nearly completed by the Ceaușescu regime as the seat of political and administrative power, though wiping out a large section of the central city. The structure of the building, and construction itself was planned at "Proiect Bucuresti" the main institution of Civil Engineering in Bucharest. The chief of the project was engineer Valentin Georgescu. Nicolae Ceaușescu named it the People's House (Casa Poporului), also known in English as the People's Palace
