Seraglio Point (Sarayburnu) (Istanbul)

The promontory separating the Golden Horn and the Sea of Marmara in Istanbul. Sight of some of the oldest settlements in what is now Istanbul (stretching back to the at least the 13th Century BC). This is where the protective sea chain anchored (from Maiden's Tower, to the east) in order to keep ships from sailing through the Bosporus without paying a toll.
