The world’s largest, most expensive and heaviest civilian administrative building, Bucharest’s Palace of the Parliament is truly an unknown wonder. “Built by hated communist dictator Nicolae Ceausescu.Built in 1984, the neoclassical building has 12 stories (with eight additional stories underground), and some 3,100 rooms covering 330,000 sqm. The project cost an unprecedented 3.3bn euros, but it also cost the people of Bucharest much of their city. To build the Palace of the Parliament, one-fifth of central Bucharest was razed, including most of its historical districts, more than 30 churches and synagogues and some 30,000 homes.
