The Topkapı Palace (Topkapı Sarayı in Turkish, literally the "Cannongate Palace" - named after a nearby gate), located in Istanbul (Constantinople), was the administrative center of the Ottoman Empire from 1465 to 1853. The construction of the Topkapı Palace was ordered by Sultan Mehmed the Conqueror in 1459. It was completed in 1465. The palace is located on the Seraglio Point between the Golden Horn and the Sea of Marmara in Istanbul, having a splendid view of the Bosphorus. It consists of many smaller buildings built together and surrounded by four courts.

The palace is full of examples of Ottoman style architecture and also owns large collections of porcelain, robes, weapons, shields, armors, Ottoman miniatures, Islamic calligraphic manuscripts and mural decorations, as well as a display of accumulated Ottoman treasures and jewelry.

In 1853, Sultan Abdülmecid decided to move his residence to the newly built Dolmabahçe Palace, the first European-style palace in the city. Today the Topkapı Palace serves as a museum for the imperial era, and is one of Istanbul's greatest tourist attractions.
