Hagia Sophia is one of the most amazing historical buildings in Istanbul. It was a basilica planned patriarchal cathedral built by the Byzantine Emperor Justinianus between the years 532-537 in the old city center of Istanbul and was converted into a mosque by Fatih Sultan Mehmet in 1453 after Constantinople was taken by the Ottomans. In 1935, Hagia Sophia became a museum. Recently, it was changed back into a mosque. Hagia Sophia is a domed basilica type that combines the basilica plan and the central plan in terms of architects and is considered as an important turning point in the history of architecture with its dome transition and bearing system features.

One of Istanbul's splendid historical buildings is the Basilica Cistern located in the southwest of Hagia Sophia. This large underground cistern built by Byzantine Emperor Justinian I (527-565) was named as Yerebatan Palace among the people due to the seemingly countless marble columns rising from the water. It is also known as Basilica Cistern since there is a Basilica in the place where the cistern is located.
