Hagia Sophia

Museum
22 mins
Hagia Sophia is the one of the most visited museums and most prominent monuments in the world in terms of art and the history of architecture. It has also been called “the eighth wonder of the world” by East Roman Philon as far back as the 6th century. The current Hagia Sophia is the third construction, done in a different architectural style, even though it occupies the same location as the previous two. The original building was constructed by the most important architects of the period (527-565), Anthemios (Tralles) and Isidoros (Miletus), under the order of Emperor Justinianos. It is mentioned in the resources that during its construction period, the two prominent architects each had 100 architects working under them, who in turn had 100 workers each working under them. The construction of the Hagia Sophia began on February 23, 532. It was completed before long, approximately within 5 years and 10 months. It was then opened to divine service with a great ceremony on December 27, 537. It was used as a church for 916 years but, following the conquest of Istanbul by Fatih Sultan Mehmed, the Hagia Sophia was converted into mosque. Afterwards, it was used as a mosque for 482 years. Under the order of Atatürk and the decision of the Council of Ministers, Hagia Sophia was converted into a museum in 1935.
Grand Bazaar

Grand Bazaar

Shopping
22 mins
The Grand Bazaar (Kapalıçarşı) in Istanbul is one of the largest covered markets in the world with 60 streets and 5,000 shops, and attracts between 250,000 and 400,000 visitors daily. It is well known for its jewellery, hand-painted ceramics, carpets, embroideries, spices and antique shops. Many of the stalls in the bazaar are grouped by type of goods, with special areas for leather, gold jewellery and the like. The bazaar has been an important trad ing centre since 1461 and its labyrinthine vaults feature two bedestens (domed buildings), 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. The complex houses two mosques, four fountains, two hamams, and several cafés and restaurants. In the centre is the high domed hall of the Cevahir Bedesten, where the most valuable items and antiques were to be found in the past, and still are today, including furniture, copperware, amber prayer beads, inlaid weapons, icons, moth er-of-pearl mirrors, water pipes, watches and clocks, candlesticks, old coins, and silver and gold jewellery set with coral and turquoise. A leisurely afternoon spent exploring the bazaar, sitting in one of the cafés and watching the crowds pass by, and bargaining for purchases is one of the best ways to recapture the romantic atmosphere of old Istanbul.
