The Metropolitan Church of the capital is dedicated to the Annunciation of the Virgin Mary and was erected during the reign of Otto (1840-1860 AD). Since its construction, the church has been the venue for ceremonies honoring prominent figures and hosting the funerals of kings and prime ministers. Within the sacred confines of the church, crafted from exquisite Larnaca marble by the skilled hands of Giannoulis Halepas, rest the revered shrouds of Patriarch Gregory V and Saint Philothea of Athens. Metropolis Square is particularly notable for the Byzantine chapel (dating back to the late 12th century) situated adjacent to the Cathedral. Initially dedicated to Panagia Gorgoepikos or Agios Eleftherios, the chapel underwent a renaming in 1863 following the expulsion of Otto, symbolizing its association with liberation from the Turks. Remarkably, the chapel eschews traditional masonry in favor of marble fragments. Adorning its exterior surfaces are raised relief plates from various epochs, including the archaic, Roman, and early Christian periods. The temple stands as an open-air museum of ancient art, seamlessly bridging the classical Greek legacy with Christian tradition. Presently, the chapel is open to visitors and serves as a place of reverence for the remains of dignitaries. Intriguingly, there are indications suggesting that its construction may have encompassed the site of the ancient temple of Eilithia, the revered patroness of childbirth.
