Interesting facts about the Palace of Westminster

The Palace of Westminster, commonly known as the Houses of Parliament lies on the north bank of the River Thames in the City of Westminster, in central London.

The Westminster Palace was originally a royal residence built in the 11th century CE for Edward the Confessor. In 1512 much of the structure was destroyed in a fire. It was rebuilt, only to be destroyed again in even greater fire in 1834.

The palace that stands today was designed by architect Charles Barry in the Gothic Revival style.

Construction started in 1840 and lasted for 30 years, suffering great delays and cost overruns, as well as the death of both leading architects; works for the interior decoration continued intermittently well into the 20th century.

The more than 300 meters (984 feet) long façade is adorned with countless sculptures, and makes the Houses of Parliament together with the strict design and unique towers one of the finest buildings in London.


The Palace of Westminster contains over 1,100 rooms, 100 staircases and 4.8 kilometers (3 miles) of passageways, which are spread over four floors.

It has a floor area of 112,476 square meters (1,210,681 square feet).

The ground floor is occupied by offices, dining rooms and bars; the first floor (known as the principal floor) houses the main rooms of the Palace, including the debating chambers, the lobbies and the libraries. The top-two floors are used as committee rooms and offices.

Westminster Hall, the oldest existing part of the Palace of Westminster, was erected in 1097, at which point it was the largest hall in Europe. Westminster Hall has the largest clearspan medieval roof in England, measuring 20.7 by 73.2 meters (68 by 240 feet).
