Just one street away to the northeast is the Hôtel des Invalides, founded by Louis XIV to shelter 7,000 aged or crippled formed soldiers. The enormous range of buildings was completed in five years (1671-76). The gold-plated dome (six kilograms of gold leaf were involved) that rises above the hospital buildings belong to the Church of Saint-Louis (1675-1706), designed by Jules Hardouin-Mansart. The architect employed a style known in France as Jesuit, since it derives from the Jesuits first church in Rome, built in 1568. The churches of the Académie Française (French Academy), the Val-de-Grâce Hospital, the Sorbonne, as well as three others in Paris, all of the 17th century, followed this style. By a freer user of the classical elements, the French made it something recognizably Parisian.
