 French Baroque profoundly influenced 18th-century secular architecture throughout Europe.Although the open three wing layout of the palace was established in France as the canonical solution as early as the 16th century, it was the Palais du Luxembourg (1615–20) by Salomon de Brosse that determined the sober and classicizing direction that French Baroque architecture was to take.For the first time, the "corps de logis" was emphasized as the representative main part of the building, while the side wings were treated as hierarchically inferior and appropriately scaled down.
