Istanbul a city worth a visit

For Example:

Istanbul - one of the most beautiful cities I have ever seen.

There is a lot things to do there.

Grand Bazaar Most guidebooks claim that it has 4000 shops. Because of consolidation and replacement of shops by restaurants and other services the number is certainly lower, but you get the idea: it has lots of shops.A dozen restaurants in the bazaar allow you to have lunch in the midst of your shopping. 

You'll want to hone your bargaining skills before you plunge into the markets.

Rumeli CastleThe Rumeli Castle was built by the Ottoman Turks in just 3 months in 1452, at the opposite shores of the earlier Anatolian Castle (1393) in order to block the entrance of the Bosphorus during the Siege Of Constantinople (May 29, 1453). 

The Castle is museum now. There is a lot of interesting things there. If you get on top of this Castle, you can see Bosphorus Bridge.

Miniatürk

This one amazed me the most. In Miniatürk you can see small models of almost all famous buildings in Istanbul.

And you can have a Delicious meal at the Miniatürk restaurant.

Galata TowerIf you are not afraid of height you can go to the Galata Tower.

There is a restaurant and café on its upper floors which command a magnificent view of Istanbul and the Bosphorus. Also located on the upper floors is a night club which hosts a Turkish show. There are two operating elevators that carry visitors from the lower level to the upper levels.

Topkapı PalaceOf all the historic sites in Istanbul, I enjoyed my visit to the Topkapi palace the most. The historical artifacts, gem collections and the view from the palace itself was just awe inspiring and breathtaking.A visit to the palace will take a good part of your day, so arrive early and enjoy the history and culture this site has to offer
