Church of Saint Menas of Samatya

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 , and on the site of an ancient church dedicated to Hagios Polykarpos.
The modern church has the same dedication as a nearby water source .

The church is located in Istanbul, in the district of Fatih, in the neighbourhood of Kocamustafapaşa , on Bestekar Hakkı Sokak. It lies inside the walled city, in an elevated position a short distance from the shore of the Sea of Marmara. The building is protected by a high wall.
The Martyrion is located under the church, on İmrahor İlyasbey Caddesi, and currently houses an iron workshop and a car wash shop. It is in a dilapidated state. Opposite to the Martyrion there is a spring also dedicated to Saint Menas.
