A world heritage site, you simply cannot visit Istanbul without visiting Blue Mosque (Sultan Ahmed). It is beautiful, both from the outside and within.

The Grand Bazaar is one of the largest covered markets in the world. It is huge, a maze of 61 streets and 3000 shops! Some guide books suggest spending several hours here, which you could, however we felt an hour was enough to walk around just some of the many streets. This gave us a flavour of the bazaar and we were able to enjoy the bustling atmosphere. The Bazaar is very busy with tourists exploring, as well as locals enjoying Turkish tea.

Historical spice bazaar where most merchants selling merchandise appealing to tourists. Baby brother of the grand Bazaar. Streets around the bazaar are more interesting than the bazaar itself.

Gorgeous tower. Very old and smelling history. A wonderful view of istanbul awaits you.

One of the most iconic building in İstanbul. You can see in city as panoramic also you can visit many important buildings with 3D video clip.

The palace/museum is very beautiful. The buildings are old and antique. We can see precious things from Islamic history and Sultan's collections. The garden is dazzling, especially when you come at spring. It takes times to go through all over museum but worth it if you love museum.

Construction completed on Hagia Sophia in 537AD. Initially Hagia Sophia was a church until 1453 when it became a mosque. Since 1935 Hagia Sophia has been a museum and today it is a world heritage site.

Beautiful gardens with historical trees, water features and meandering paths. Entrance is free and it's next to the Topkapi Palace. Nice place to escape the hustle and bustle of Sultanahmet.

Located in the Sultanahmet district, over the road from Hagia Sophia, this Cistern constructed 527-565AD is unusual. Inside are 336 marble columns and 2 Medusa heads. It is certainly different, you won't need more than about half an hour inside.

Construction on the Suleymaniye Mosque completed in 1557. It is one of the most popular mosques in Istanbul and is beautiful. The ceiling is amazing so take plenty of time to admire this. This is less busy than the Blue Mosque however it is still definitely worth visiting.

Serpentine Column. It was cast by the Greeks after their victory over the Persians at the Battle of Plataea in the 5th century BC. The remains of the former glory of the ancient Greeks.

Great mosque, with some reconstruction works nowadays.
