Blue Mosque

The Blue Mosque is an 18th-century Shia mosque in Yerevan, Armenia. It was commissioned by Hoseyn Ali Khan, the khan of the Iranian Erivan Khanate. It is one of the oldest extant structures in central Yerevan and the most significant structure from the city's Iranian period. It was the largest of the eight mosques of Yerevan in the 19th century and is the only active mosque in Armenia today.

The mosque was secularized in the 1920s and housed the History Museum of Yerevan for more than five decades. Following Armenia's independence, the mosque was renovated with support from the Iranian government and again started operating as a mosque, serving the Muslims residing in Armenia.
