Its name, which is derived from the neighbouring Westminster Abbey, may refer to either of two structures: the Old Palace, a medieval building complex destroyed by fire in 1834, and its replacement, the New Palace that stands today. The palace is owned by the monarch in right of the Crown and for ceremonial purposes, retains its original status as a royal residence. The building is managed by committees appointed by both houses, which report to the Speaker of the House of Commons and the Lord Speaker.
The first royal palace was built on the site in the 11th century, and Westminster was the primary residence of the Kings of England until fire destroyed much of the complex in 1512. After that, it served as the home of the Parliament of England, which had been meeting there since the 13th century, and also as the seat of the Royal Courts of Justice, based in and around Westminster Hall. In 1834, an even greater fire ravaged the heavily rebuilt Houses of Parliament, and the only significant medieval structures to survive were Westminster Hall, the Cloisters of St Stephen's, the Chapel of St Mary Undercroft, and the Jewel Tower.
The subsequent competition for the reconstruction of the Palace was won by the architect Charles Barry, whose design was for new buildings in the Gothic Revival style, specifically inspired by the English Perpendicular Gothic style of the 14th–16th centuries. The remains of the Old Palace (except the detached Jewel Tower ) were incorporated into its much larger replacement, which contains over 1,100 rooms organised symmetrically around two series of courtyards and has a floor area of 112,476 m2 (1,210,680 sq ft).
