Following the renaissance and the end of the Middle Ages, Baroque architecture replaced the traditional Gothic style. However, in France, baroque architecture found a greater success in the secular domain than in a religious one. In the secular domain, the Palace of Versailles has many baroque features. Jules Hardouin Mansart, who designed the extensions to Versailles, was one of the most influential French architect of the baroque era; he is famous for his dome at Les Invalides. Some of the most impressive provincial baroque architecture is found in places that were not yet French such as Place Stanislas in Nancy. On the military architectural side, Vauban designed some of the most efficient fortresses in Europe and became an influential military architect; as a result, imitations of his works can be found all over Europe, the Americas, Russia and Turkey.
