Mezquita-Iglesia de El Salvador, Toledo
Toledo, Spain
The Iglesia de El Salvador is a church in Toledo, Spain completed in 1159. Although the church is small, it is an exceptional building, because it was the site of 4 successive constructions, one on other and so on. It is a 12th-century church built on an 11th-century Taifa mosque, which was an expansion of a 9th-century Umayyad mosque and in turn on a Visigothic religious building.
