Beşiktaş gained its identity as a settlement during the Ottoman period.During the Byzantine period, the Bosphorus was subjected to raids by Georgian marauders, especially those coming from the Black Sea , and the destruction and fear they caused prevented the development of settlements outside the walls. Beşiktaş gained the identity of a settlement during the Ottoman period thanks to the Black Sea being largely under the control of the Ottoman Empire.The area where Beşiktaş is located was a bay suitable for use as a port at that time. Barbaros Hayreddin used Beşiktaş Bay to anchor the ships of the Ottoman navy . Beşiktaş bay began to be filled in the 17th century . This area was turned into a "private garden" for the rest and entertainment of the sultans. The collection of mansions and pavilions built in this garden in various periods was known as Beşiktaş Beach Palace for a long time.
