Martyrion of Hagios Karpos and Papylos (Constantinople)
Saint Menas  (Greek: Ἄγιος Μηνάς, pr. Ágios Minás; Turkish: Ayios Minas Kilisesi) is a Greek Orthodox Church in Istanbul. The edifice was built in 1833 near an early Christian Martyrion of the fourth or fifth century, possibly dedicated to the saints Carpus and Papylus (Greek: Μονὴ τῶν ἁγίων Κάρπου καὶ Παπὺλου, Monì ton Agíon Kárpou kai Papýlou ), and on the site of an ancient church dedicated to Hagios Polykarpos. The modern church has the same dedication as a nearby water source (Greek: Hagiásma, Turkish: Ayazma).
