Across the Seine from the Louvre, Louis XIV built the Collège des Quatre-Nations (College of the Four Nations) (1662–1672), an ensemble of four baroque palaces and a domed church, to house students coming to Paris from four provinces recently attached to France (today it is the Institut de France). He built a new hospital for Paris, the Salpêtrière, and, for wounded soldiers, a new hospital complex with two churches: Les Invalides (1674). In the centre of Paris, he constructed two monumental new squares, the Place des Victoires (1689) and the Place Vendôme (1698).
