Pasabahce, a Bosphorus village on the Anatolian Side, was originally a Greek settlement. Muslims began to settle there in the second half of the 18th century. The centre of Pasabahce, on the shore, has a texture of attached structures. In the surroundings, many wooden houses and mansions which are located in large gardens, shape the settlement. The mansions are thought to have been used as summer houses by senior government officials. Two mansions located at Sunaziri Street and Sekerpare Street in Pasabahce are the subject of this article. Despite the uncertainty of the construction dates of the two mansions, it is estimated that they were built in the mid-19th century. Considering the construction dates, they are probably two of the oldest existing structures in Pasabahce.
