The Seven Mosques
Medina, Saudi Arabia
The Seven Mosques (al-Masājid al-Sabʿa) is a complex of six small historic and often visited mosques in the city of Medina, Saudi Arabia. Despite only consisting of six mosques, the complex is called seven because some think it originally consisted of seven mosques. Another reason for the name is that many visitors usually visit Masjid Al-Qiblatayn among these mosques on their visit to Medina, making it seven. Some also consider Masjid al-Khandaq to be among one of those seven mosques.
