BEWARE Any bus or tram with a sign or indication that it heads for or calls at Topkapı will NOT take you anywhere near Topkapı Palace. Rather it will to a neighbourhood named after the city gate near which it’s situated (“cannon gate”), which may be worth a trip to take a look at the impressive city walls. Topkapı neighbourhood is located in the extreme western part of the old city, near the city walls, while Topkapı Palace is located in the extreme eastern part, which means the distance between each other is at least 7-8km. ‘Topkapı’ alone almost always refer to the neighbourhood, not the palace. Taking a bus heading for Topkapı to go to the palace is a common mistake made by visitors. For the palace, the stop/station you should look for is 'Sultanahmet'.
