In the early 17th century, hundreds of thousands of Christian Armenians from northwest Iran were resettled in Esfahan by Shah Abbas – Vank Cathedral is the most impressive of their subsequently constructed places of worship. The outside of the cathedral is fairly plain, yellowy-brown brickwork. By contrast, the inside boasts elaborate and colourful frescoes, containing some disturbing depictions of the terrors of hell. There is also a fascinating museum (which displays Shah Abbas’ original edict establishing the new Armenian town), and a memorial to the Armenian Genocide.
