The Imperial Palace in the centre of Beijing, China covers a rectangle measuring 960 x 750 m (3,150 x 2,460 ft) over an area of 72 ha (178 acres). The outline survives from the construction of the third Ming Emperor, Yongle (1402-24), but owing to constant reconstruction work, most of the intra-mural buildings (five halls and 17 palaces) are from the 18th century.
The Palace of Versailles, 23 km (14 miles) south-west of Paris, is 580 m (1,902 ft) long and has a facade with 375 windows. The building, completed in 1682 for Louis XIV, occupied over 30,000 workmen under Jules Hardouin-Mansart (1646-1708).
