Largest socialist state palace

The largest palace in the world used for a socialist state government and leader is the Palace of the Parliament in Bucharest, Romania, which was mostly constructed between July 1984 and 1989 during the regime of the Romanian Communist Party and its then head Nicolae Ceauşescu. Housing the two chambers of the Romanian parliament, the massively imposing neoclassical structure contains 1,100 rooms and parking spaces for 20,000 cars across a 340,000-m² (3,700,000-ft²) floor area. It measures 270 m (890 ft) by 240 m (790 ft), and rises 86 m (282 ft) above ground with another 92 m (302 ft) of subterranean levels. The palace was designed by 25-year-old architect Anca Petrescu, working with a team of more than 500 people, and was constructed by Aedificia Carpati using 20,000 workers.
