Issy-Kul Central Mosque of Karakol was built by Ibrahim Aji. He invited the famous Beijing architect Chou Seu, along with 20 carvers, skilled in traditional Chinese architecture for building the mosque. Construction of the mosque began in 1904 and was completed in 1910. Through an ingenious system, the builders did not use any nails in the construction of the building. From 1929 to 1947, during the Soviet era, the mosque was used as a storehouse. In 1947, the building was given back to the Muslim community, and since then has been used as a mosque. It is registered as a historical monument and protected by law. Also known as Dungan Mosque, this site is open to tourists. It is a beautiful and unique structure worth seeing! Please dress appropriately, but know they do have headscarves and long coats for you to wear while inside.
