Wikipedia states The Grand Bazaar (or Covered Bazaar, Turkish: Kapalicarsi ) in Istanbul is one of the largest covered markets in the world with more than 58 streets and 4,000 shops, and has between 250,000 and 400,000 visitors daily. It is well known for its jewelry, pottery, spice, and carpet shops. Many of the stalls in the bazaar are grouped by type of goods, with special areas for leather coats, gold jewelry and the like. 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.
