This beautiful church is located near new Metropolitan. It was built in the end of 12th century in honor of Panagia Gorgoepikoo and Aghios Eleftherios. For its construction many ancient and Byzantine bas-reliefs were used. On its front there is an ancient frieze that comes from a monument dating back to the 4th century and revives the formal Attica celebrations. It became the orthodox Episcopal center of Athens, when all bishops were chased away from Parthenon, firstly by the Franks and later by the Turks, while from 1839 until 1842 it housed a library. The neighboring new Metropolitan was built between 1842 and 1862 as Athens Cathedral. It is a three aisled domed basilica that combines neo Byzantine and neo classic elements.
