A simple hunting lodging and later a small château with a moat occupied the site until 1661, when the first work expanding the château into a palace was carried out for Louis XIV. In 1682, when the palace had become large enough, the king moved the entire royal court and the French government to Versailles. Some of the palace furniture at this time was constructed of solid silver, but in 1689 much of it was melted down to pay for the cost of war. Subsequent rulers mostly carried out interior remodeling, to meet the demands of changing taste, although Louis XV did install an opera house at the north end of the north wing for the wedding of the Dauphin and Marie Antoinette in 1770. The palace has also been a site of historical importance. The Peace of Paris (1783) was signed at Versailles, the Proclamation of the German Empire occurred in the vaunted Hall of Mirrors, and World War I was ended in the palace with the Treaty of Versailles, among many other events.
