Church of Panaghia Gorgoepikoos in Athens

This church, set right next to the Cathedral of Athens, is a structure of the late 12th Century and the successor of a Greek temple to the goddess Eileithyia. Originally known as the Little Metropolis, the site was dedicated to Saint Gorgoepikoos and was part of Athens' episcopal property.

Towards the end of the Medieval period, the church was known both as St Gorgoepikoos and Catholicon, and by the mid-19th Century, it was already converted into a public library. Then, in 1863, the site was dedicated to St Eleutherios. The building itself is comprised of massive Greek, Roman and early Byzantine marble blocks, some of them having been taken from nearby ruins. It also has impressive relief plaques, although it largely lacks the typical red brick decorative patterns. The reliefs can be viewed on the walls' upper ends. The dome is an example of cloisonne masonry.
