The Palace of Versailles, or Château de Versailles, is a building that served as a royal residence from 1682 to 1789. The palace is located in the commune of Versailles, near Paris, in the Ile-de-France region of France. It is one of the most important monarchical architectural complexes in Europe and in 2018 it exceeded eight million visitors for the first time.

Versailles comprises three palaces: Versailles, the Grand Trianon and the Petit Trianon, as well as several buildings in the village. Although Louis XIII had a hunting lodge with a garden built there, Louis XIV is its true creator, as he gave it its size and determined its destiny. Initially, the architect Charles Le Brun and his team added two side wings to the hunting lodge which, when enclosed, formed the parade ground. In the second stage (1668-1678), the two side wings were added to give visual priority to the garden, designed by André Le Nôtre, and in the third and final stage (1678-1692), designed by Jules Hardouin-Mansart, the royal chapel was built at double height and with direct access from the outside, the royal tribune being located on the main floor.

The Palace of Versailles has been administered since 1995 by the public establishment of the Museum and National Domain of Versailles, a public entity operating under the control of the French Ministry of Culture. The entire palace and park of Versailles, including the Grand Trianon and the Petit Trianon, was declared a UNESCO World Heritage Site in 1979.
