Following the papal letter dated 2 July 1895, the church and its annexes were transferred to the administration of the Assumptionist Fathers.
A monastery building complementing the main structure was added to the church complex.
From the mid-1970s to the present, the building has also been used as a place of worship by the Syriacs.
Prominent Features:
The church belongs to the Latin Catholic Church.
The building is also known as the “Kadıköy French Catholic Church” and the “Church of the Assumption.”
The church is in the Neoclassical style.
The building has a domed cruciform plan; on the west façade, two bell towers strongly define the façade composition.
In the Latin inscription on the façade, the architect’s name appears as “Architectus Johannes Barborini.”
The languages of worship in the church are French and Turkish.
A decree dated 1859 granted the necessary permission for the construction of the building.
In 1858, the Apostolic Vicar Monsignor Brunoni assigned Father De Negri to establish a church in Kadıköy; newly arrived Catholics from Chios made a concrete contribution to the construction process.
