Puertas de Tierra is a bastion-monument built around remnants of the old defensive wall at the entrance to the city of Cadiz. Built by academic architect Torcuato Cayón in the 18th century, the cover is carved in marble and was intended more as a religious altarpiece than as a military fortification.
It is one of the most significant monuments of the city and on its walls flies the purple flag of its canton.
The adjustment to the new architecture of the city, opening the two new arcs, is performed by the architect Antonio Sánchez Esteve.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
