Grand Bazar 

The Grand Bazaar (or Covered Bazaar, Turkish: Kapalıçarşı ("Covered Bazaar")) in Istanbul is one of the largest covered markets in the world with more than 58 streets, over 1200 shops, and has between 250000 and 400000 visitors daily. It is well known for its jewelry, pottery, spice, and carpet shops. The bazaar contains two bedestens (domed masonry structures built for storage and safe keeping), the first of which was constructed between 1455 and 1461 by the order of Sultan Mehmed the Conqueror. The bazaar was vastly enlarged in the 16th century, during the reign of Sultan Suleiman the Magnificent, and in 1894 underwent a major restoration following an earthquake. (Wikipedia)
