The Great Mosque of Seville is the third largest mosque in the Islamic West. It was founded by Abu Ya'qub Yusuf, the second caliph of the Almohad state.
The construction of the mosque began in Ramadan 1172, so the house inside the Kasbah was demolished, and the place was vacated to house this great landmark. The mosque was inaugurated on April 14, 1182, in a ceremony attended with his crown prince, all his sons and the elders and notables of the city.
