At the intersection of Bosporus Strait, Golden Horn Bay and Marmarak Sea, there is a splendid building, which was the center of the Ottoman Empire from 15 to 19 century-Topkapu Palace, which was the maze where the Sultans worked in those years and was also an extremely luxurious place. Outside the palace is the lush first courtyard in Lvmu, which used to be the second courtyard of the palace restaurant, and now it has become a collection of crystal products, silverware and China ceramics in the imperial era. On the left is the Sultan's harem, where all kinds of conspiracies take place. In the third yard, there is a reception room, a library, a clothing and jewelry museum (you can see the second largest diamond in the world) and priceless medieval painting books. At the center of the palace is the sacred room.
