Mustafa Kemal Atatürk, the founder and the first president of Turkey, used to spend his free time in his Florya Atatürk Marine Mansion swimming and enjoying the beautiful sandy beach.

Florya's name, according to the Byzantine scholar Michael Psellos, who found it cited in an imperial Chrysobull, comes from the Greek word "Phlorion". It is possibly derived from a certain Florus, who lived in this neighborhood during the early Byzantine age. Until the 1920s the Ottoman name was "Fülürye".

One part of the neighborhood is also called Şenlikköy.

The Atatürk Marine Mansion, once summer residence of Mustafa Kemal Atatürk and a museum today, is located at the shore of Marmara Sea.
