Alcazaba of Badajoz
Badajoz, Spain
The Alcazaba of Badajoz is an ancient Moorish citadel in Badajoz, Extremadura, western Spain. The alcazaba, as it now appears, was built by the Almohads in the 12th century, although it probably existed from the 9th century, when Badajoz was founded. In the 11th and 12th centuries, it was the residence of the taifa of Badajoz rulers. It was declared a national monument of Spain in 1931.
