The Palace of the Parliament in Bucharest, Romania (known before the 1989 revolution as the Republic House or People’s House), measures 270 m by 240 m, 86 m high, and 92 m underground made in the spirit of realistic socialist architecture. It has 9 levels on the surface and another 9 underground. According to the World Records Academy, the Palace of Parliament is the second largest administrative building for civilian use in the world, and the most expensive administrative building in the world and the heaviest building in the world. The Parliament Palace building is located in the central part of Bucharest (sector 5), on the place now called Arsenal Hill, surrounded by Izvor Street to the west and northwest, United Nations Boulevard to the north, Liberty Boulevard to the east and Calea 13 Septembrie the south. It is 10 minutes away from Unirii Square and 20 minutes from the North Railway Station (by bus 123).
The hill on which the Parliament Palace stands today is generally a creation of nature, with an initial height of 18 m, but the part from Libertății Boulevard is artificially raised.
It ranks second in the world in terms of “the most expensive, unsuccessful and shameful architectural projects ever made”, a ranking made by the most visited architectural site in the world, ArchDaily. Although it cost and costs enormously in money and suffering , 70% is unused, most of it not being structured for the needs of individuals but for the megalomaniacal desires  of Ceaușescu, the cult of personality putting its mark on this building.
After the earthquake of March 4, 1977, the communist dictator Nicolae Ceaușescu found the pretext for changing the capital according to political realities, namely the fact that Romania was a socialist state, so a realistic socialist architecture was wanted. An idea of King Carol II from 1935 was taken over, in whose project the construction of the Chamber of Deputies on the Arsenal Hill was foreseen. This project had been designed by the greatest architects of the time. In 1938 it was announced the start of demolition in order to open this axis. World War II came and things remained only on paper until 1983, when the construction of the “People’s House” began, a monstrous monument of totalitarian kitsch, the official ceremony of laying the foundation stone taking place on June 25, 1984.
The building has an area of 330,000 m², registering, according to World Records Academy, in the chapter “Administrative Buildings”, on the 2nd place in the world after the Pentagon building, and in terms of volume, with its 2,550,000 m³ , ranked 3rd in the world, after the space rocket assembly building at Cape Canaveral in Florida and after the pyramid of Quetzalcoatl in Mexico. For comparison, it can be mentioned that this building exceeds by 2% the volume of the pyramid of Cheops in Egypt, and therefore some sources characterize it as a “pharaonic” construction.
Started during the communist regime (self-titled “Golden Age” of Romania and violently removed by the 1989 Revolution), the so-called Bucharest Project was an ambitious project of the Ceausescu couple started in 1978, as a replica of the city Pyongyang, the capital of North Korea. A systematization project has existed since the 1930s (from the time of Charles II) for the Union – Arsenal Hill area.
After the 1977 earthquake, Nicolae Ceausescu ordered the “reconstruction” of Bucharest as a new city, on its own. In the years 1978-79, a national competition took place for the reconstruction of Bucharest. The contest lasted almost 4 years and was won by Anca Petrescu, a young architect only 28 years old, who was named chief architect of this exceptionally controversial project.
The construction site itself began in the 1980s with the demolition of over 7 km² of the old center of the capital and the relocation of over 40,000 people in this area. Among the missing buildings are the Văcărești Monastery, the Brâncovenesc Hospital, the National Archives, the Republic Stadium, etc. The works were carried out with the forced labor of the military on time and thus the cost was reduced to a minimum.
This project for the reconstruction of Bucharest included a series of buildings such as: Parliament Palace – Republic House, Ministry of National Defense, Radio House, Marriott Hotel – Guest House, Romanian Academy House, Izvor Park and Unirii Boulevard – Victoria Socialismului.
In 1989 the cost of the building was estimated at 1.75 billion US dollars, and in 2006 at 3 billion Euros.
20,000 workers, 5,000 soldiers, 700 architects, an army of so-called “volunteers” worked in difficult conditions, 3 shifts for 7 years. The number of victims is not known, this being a taboo subject, the communist authorities not wanting to publish the data, those who worked on this site declare that they were victims, taking into account the number of victims on other sites the size of the “People’s House” made in the “communist era” “We can say that there were hundreds of deaths.
