Most of them are surmounted by bright-coloured cupolas and minarets.
The façade, flanked by two towers with cupolas, is decorated with arcades filled in with statuary and sculpture, the whole representing the Last Judgment.
Marble terraces and balustrades surround the tank, and a marble causeway leads across the water to the temple, whose gilded walls, roof, dome and cupolas, with vivid touches of red curtains, are reflected in the still water.
The New Mosque (Jamaa-el-Jedid), dating from the 17th century, is in the form of a Greek cross, surmounted by a large white cupola, with four small cupolas at the corners.
Of the principal mosques the large Buyuk Djamia, with nine metal cupolas, has become the National Museum; the Tcherna Djamia or Black Mosque, latterly used as a prison, has been transformed into a handsome church; the Banyabashi Djamia, with its picturesque minaret, is still used by Moslem worshippers.
