Many places of tourist interest are concentrated in Sultanahmet, heart of the Imperial Centre of the Ottoman Empire. The most important places in this area, all of which are described in detail in the “Places of Interest” section, are Topkapi Palace, Aya Sofia, Sultan Ahmet Camii (the Blue Mosque), the Hippodrome, Kapali Carsi (Covered Market), Yerebatan Sarnici and the Museum of Islamic Art.
In addition to this wonderful selection of historical and architectural sites, Sultanahmet also has a large concentration of carpet and souvenir shops, hotels and guesthouses, cafes, bars and restaurants, and travel agents.

The first of the seven hills on the promontory has been the most important and dynamic part of the city in all ages. When the city was first founded, the acropolis was a typical Mediterranean trading center surrounded by city walls. This trading center was enlarged and rebuilt during Roman times. The most prominent buildings and monuments of the Roman era were built in the vicinity of the Hippodrome. Very few relics of these works have endured to the present day.
The imperial palace, known as the "Great Palace", used to spread over an area extending from the Hippodrome down to the seashore. Only the mosaic floor panel of a large hall remains from this palace today. The Augusteion, the most important square of the city, used to be here, and between the square and the main avenue there was the Millairium victory arch. The road used to extend as far as Rome and the stone marking the first kilometer was located here. The baths, temples, religious, cultural, administrative and social centers were all in this district. The area maintained its importance in the Byzantine and Turkish eras. Therefore some of the most important monuments of Istanbul such as the Hagia Sophia, Sultan Ahmet Mosque, the Museum of Turkish and Islamic Art and the Basilica Cistern are all located around the Hippodrome.

The main streets in the city (those leading down to the harbor and those extending toward the city walls in the west) started at the Hippodrome and followed the slopes of the hills. The streets were lined with business establishments and mansions. The side streets were narrow and some were stepped. Some of the main streets had two-galleried sidewalks. There were spacious squares along the route and the side roads forking from these squares led to the city gates. The main avenue was called the Mese, and Via Egnetia, the road to Rome, started at the Golden Gate (Altmkapi).
