This tiny church with its three domes looks as if it would fit nicely into a miniature village. It has some fine frescoes, but its real glory is its facade, with windows piled above windows, domes above domes. Like the Panagia Acheiropoietos, the 11th-century Panagia Chalkeon now sits considerably below Thessaloniki's modern street level. Some of the copper-workers' shops, from which this church took its name centuries ago, survive nearby. Locals call this the "red church" for its rosy bricks.
