Westminster Cathedral
The site on which the cathedral stands in the City of Westminster was purchased by the Diocese of Westminster in 1885, and construction was completed in 1903. Westminster Cathedral is the largest Catholic church building in England and Wales and the seat of the Archbishop of Westminster.
World's largest palace
England's Palace of Westminster was built in the Middle Ages as a royal residence. It served as the principal residence of the monarch until 1522, when Henry VIII moved his court to the newly acquired Palace of Whitehall. Since that time, the palace at Westminster has been used by the House of Lords, the House of Commons and various courts. The majority of the medieval palace was destroyed by fire in 1834, with construction of the current building starting in 1840. The palace which now stands on the site was designed specifically for parliamentary use, however it is the property of the monarch in right of the Crown and retains its status as a royal residence. Very little of the medieval palace survived, but the most significant is Westminster Hall, built in 1097 during the reign of William II.
