The Alcazaba of Antequera was erected in the 14th century to counter the Christian advance from the north, over Roman ruins.
The fortress is rectangular in shape, with two towers. Its keep (Torre del homenaje, 15th century) is considered amongst the largest of Moorish al-Andalus, with the exception of the Comares Tower of the Alhambra. It is surmounted by a Catholic bell tower/chapel (Templete del Papabellotas) added in 1582.
Connected to the former by a line of walls is the Torre Blanca ('white tower').
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.
