10 Oldest Mosques in the World

01. Quba Mosque, Saudi Arabia

First Built: 622

Even here, there is the distinction between old mosque buildings that have been in continuous use as mosques, and those that have been converted to other purposes; and between buildings that have been in continuous use as mosques and those that were shuttered for many decades.
