The Juma Mosque, or Friday Mosque of Nakhchivan, forms part of the historic Atabegs' Complex along with the Momine Khatum and Yusif ibn Kuseyir mausoleums. It is a relatively plain brick building with a substantial dome and arched portal, reflecting the local medieval tradition. The mosque suffered serious damage and decay over the centuries and was reconstructed several times.
Inside, the prayer hall is sparsely decorated. The setting matters more than the interior: the mosque anchors the complex of medieval monuments that defines old Nakhchivan, with the slender ten-sided mausoleum a few steps away. Visit together with the Momine Khatum and the statue of the architect Ajami.
