[1] The church building was initially constructed in wood by Europeans in early 16th century on the uphill of Galata in Constantinopleto be used by the servants of the diplomatic missions in Pera.

According to a handwritten document bearing the seal of the Ottoman Sultan, the wooden church and its real estate were purchased in 1515 by the Armenian community from Greeks in 1515.

The Church of Galata served the community ten years long until it was closed down by the priests and the trustees.

The western facade and all the corners and windows are accentuated with marble ornaments giving a rustic architecture appearance.

External decorations are doorposts, rectangular windows with stone frame, metallic black painted doors of the church and the annexes enriched with gold color, marble inscriptions, half-round-arched and oval windows with metallic radial ornaments as well as sharp-profiled moldings between the stories.

The narthex at the western entrance is divided symmetrically by inline-standing three fluted columns with Corinthian capital, which bear the gallery atop.

The interior of the church is dusky despite the rectangular windows lined up symmetrically on the northern and southern sides.

The inner walls are decorated with plasters of fluted Corinth column, arches on windows, keystones with crucifix motifs, cornices, cantilevers with acanthus reliefs under the vaults, alternate lined rosette decorations as well as the ornaments in Ancient Greek and Ancient Roman architectural style on the half-round ceiling of the apse.

[1] Oil painting portraits of the apostles and the four Evangelists are found inside rectangular frames as part of a vault in the form of a large-sized elliptical arc.

The gilded altar and the choir is separated from the nave by a latticework wooden railing with star motifa.
