Trabzon Ayasofya Church which serves as a museum today was constructed in the time of Manuel Comnenos I (1238-1263), one of the kings of Trabzon Empire. The bell tower to the west of the church was dated back to 1427 by the British traveller and researcher G. Finlay. On the west of the church are the remains of a chapel with three apses which is supposed to have belonged to an earlier period.

There is almost no scientific litterateur about the history of Koprubasi and the first habitation process. According to the information we got; some of the Turkish tribes which migrated from Central Asia came to Trabzon after the conquest and were placed in some available areas. Before the settling, Koprubasi was full of rich forests and the sun could not heat the soil due to the density of trees.

There are plenty of historical artifacts in a narrow area in Ortahisar neighborhood. The oldest one among these artifacts is Altinbasli Meryemana Church (Panaghia Khrysokephalos Virgin Church) dated 914. It was converted to a mosque and started to be known as Fatih or Ortahisar Mosque. Mehmet Sultan, the Conquerer has performed his first Friday prayer here. The residence opposite to this mosque is the house where Suleiman the Magnificent lived. The house serves as a museum today.

Located in the Kemerkaya Neighbourhood, the church was built for the foreign citizens around 1869 and 1874 upon the order of Sultan Abdülmecit. Since then, the church has still been used for worship by foreign citizens and visitors.
