トプカプ宮殿
The imperial structure, a former part of the Topkapı Palace complex, is situated on top of the ancient Golden Horn Wall at Marmaroporta ("Marble Gate") () just below Topkapı Palace. It was erected next to, yet no more existing, Yalı Köşkü, a waterfront pavilion, which was built by Selim I and served to many sultans as a place for reception of Kapudan Pashas (fleet admirals) and for salutation of the fleet before setting sail to a campaign or after returning from a campaign.
