The Genoese built Galata Tower in the 14th century, and at 67 meters it still stands out on the skyline with its stone walls and conical roof. Over the centuries it served as a watchtower and later as an observatory for astronomy. Today people climb it for the view: a full 360-degree sweep that takes in the Bosphorus, the Golden Horn, and the Historic Peninsula. Sunset and evening are the popular hours, for good reason. The surrounding Galata neighborhood deserves time of its own, with boutique shops, cafés, and a busy nightlife scene in the cobbled streets below the tower, so plan a full afternoon.

This site is still part of daily city life, which is rare for a monument this old. Byzantine emperors and Ottoman sultans both built here, often on the same foundations. The layers are easy to spot once you know what to look for.

Visitors interested in Byzantine and Ottoman architecture will want extra time here. Photographers usually come early, before the crowds arrive and while the light is low.

First-time visitors and solo travelers both manage easily here. The area is walkable, and staff at most sites are used to tourists.

Nearby bazaars sell Turkish crafts and souvenirs. Tea houses in the side streets are a good place to rest between sights.
