The Cordoba cathedral mosque or mezquita-catedral de Cordoba is quite extraordinary. The architecture and decoration are sumptuous. It has changed religions several times over the centuries and is an incredible mix of Moorish and European architecture. The great mosque was built in 785 on the site of a Visigoth basilica. It was then expanded many times up to the late 10th century until it was able to accommodate 40 000 people. It was turned into a cathedral in 1236. The structure remained much the same until the 16th century when a Renaissance nave and transept were inserted into the middle. I’ve tried to illustrate these changes in the following photos.
