Top Capou (i.e. Top Kapı), Constantinople, Turkey


This photochrome print showing the Topkapi Gate in Constantinople (present-day Istanbul) is part of “Views of People and Sites in Turkey” from the catalog of the Detroit Publishing Company (1905). Top kapi means “Cannon Gate.” Cannons, which also gave their name to the Topkapi Palace in Constantinople, were the key to the conquest of the city by Mehmed II in 1453. They enabled him to breach the city walls for only the second time since they were fortified by Emperor Theodosius II in the fifth century. The gate and the walls were described in the 1911 edition of Baedeker’s The Mediterranean, seaports and sea routes: Handbook for Travellers: “This was originally a single wall, defended by towers, but after an earthquake in 447 it was doubled, the two walls being 66 yards [60.35 meters] apart and, from the bottom of the moat, 100 feet [30.48 meters] high."

  • The Detroit Photographic Company was launched as a photographic publishing firm in the late 1890s by Detroit businessman and publisher William A. Livingstone, Jr., and photographer and photo-publisher Edwin H. Husher. They obtained exclusive rights to use the Swiss "Photochrom" process for converting black-and-white photographs into color images and printing them by photolithography. This innovative process was applied to the mass production of color postcards, prints, and albums for sale to the American market. The firm became the Detroit Publishing Company in 1905.
