View looking south over part of Istanbul where the Golden Horn enters the Bosporus.
In the upper portion of the image is the Sea of Marmara.
The water on the left (east) side of the image is the Bosporus Strait. On the Bosporus, note the single bridge (in this image) and all of the ships.
The "Golden Horn" (river) "flows" from right to left in the center of the image—entering the Bosporus.
The landmass on the right (west) side of the Bosporus is European Istanbul. That on the left (east) side of the Bosporus is Asia.
