Castillo de Niebla, Niebla

The castle of Niebla, also known as the castle of Los Guzmanes, is a Spanish fortification located in the Andalusian municipality of Niebla, in the province of Huelva. The building, located at one end of the Andalusian citadel built during the Taifa of Niebla, has a quadrangular floor plan, divided into two large courtyards surrounded by square towers. The keep rises in the northeast corner and has a square floor plan topped by defensive battlements. The material used in the construction is a mixture of ashlars, stone ashlars and rammed earth.

Although the castle has Roman, Visigothic and Andalusian remains, the construction of the current building is after the Reconquest and the creation of the county of Niebla, being the II Duke of Medina Sidonia the builder of the current castle. The earthquake of 1755 caused serious damage to both the walls and the castle, but mainly to the keep. During the War of Independence, part of the walls and the castle were destroyed by the French troops.
