Blenheim Palace (in England) and Hamilton Palace (in Scotland, demolished in 1927) are the only non-royal and non-episcopal residences to have the word "palace" in their name, other than Dalkeith Palace in Scotland, which used to be the seat of the Dukes of Buccleuch (who descend from Charles II of England). Turkey After the conquest of Istanbul by Mehmed the Conqueror at 1453, construction of the Topkapı Palace was started in the year 1460 and completed in 1478. The palace was built upon a 700,000 square meter area on an Eastern Roman Acropolis located on the Istanbul Peninsula between the Sea of Marmara, Bosphorus and the Golden Horn. Topkapı Palace was the administrative, educational, and art center of the Empire for nearly four hundred years from Mehmed the Conqueror until Sultan Abdulmecid who was the thirty-first Sultan. Although Topkapi Palace was abandoned by the Ottoman Dynasty by moving to the Dolmabahçe Palace in the middle of the 19th century, Topkapı Palace retained its importance. After the establishment of the Republic of Turkey, Topkapı Palace was transformed into a museum on 3 April 1924. It was also the first museum of the Republic of Turkey. Topkapı Palace Museum covers approximately 400,000 square meters at the present day. Topkapı Palace is separated from the city on the land-side by the Imperial Walls, which were constructed by Mehmed the Conqueror. It is separated from the city on the sea-side by the Byzantine Walls. Topkapı Palace is one of the largest palace-museums with its architectural structures, collections, and approximately 300,000 archive papers.

(To this day many bishops' palaces house both their family apartments and their official offices.) However, unlike the "Palais du Justice" which is often encountered in the French-speaking world, modern British public administration buildings are never called "palaces"; although the formal name for the "Houses of Parliament" is the Palace of Westminster, this reflects Westminster's former role as a royal residence and centre of administration. In more recent years, the word has been used in a more informal sense for other large, impressive buildings, such as The Crystal Palace of 1851 (an immensely large, glazed hall erected for The Great Exhibition) and modern arenas-convention centers like Alexandra Palace. The largest in the world is the Palace of
