Wilanów Palace Warsaw Poland...Wilanów Palace was built for the Polish king John III Sobieski in the last quarter of the 17th century and later was enlarged by other owners. It represents the characteristic type of baroque suburban residence built entre cour et jardin (between the entrance court and the garden). Its architecture is original - a merger of European art with old Polish building traditions. Upon its elevations and in the palace interiors antique symbols glorify the Sobieski family, especially the military triumphs of the king..
