Istanbul Historic Peninsula Guide: Hagia Sophia, Sultanahmet and Topkapı

Straddling two continents, Istanbul is one of the rare cities to have been capital to three empires. The place where that history is most concentrated is the Historic Peninsula, stretching between the Golden Horn and the Sea of Marmara. With its monuments within walking distance of one another, it is the natural starting point for first-time visitors.

Hagia Sophia and Sultanahmet Square

Once the largest church in the world, then a mosque, later a museum and today a place of worship once more, Hagia Sophia is a turning point in the history of architecture. Its vast dome and golden mosaics still astonish everyone who steps inside. Directly opposite, the Blue Mosque brings graceful balance to the square with its six minarets and blue İznik tiles. The plaza between the two is the ideal place to begin.

Topkapı Palace and the Basilica Cistern

Topkapı Palace, from which Ottoman sultans ruled for centuries, easily fills half a day with its courtyards, treasury and terraces overlooking the Bosphorus. A few steps away, the dim, cool Basilica Cistern, supported by hundreds of columns, is the city's most atmospheric underground space. Arriving early is a smart way to avoid the crowds.

The Grand Bazaar and practical tips

You can end your walk at the Grand Bazaar, one of the oldest covered markets in the world, where getting lost among thousands of shops is an experience in itself. Buying tickets in advance for the museums and palaces spares you the queues, and combined passes for the main sights are good value. Comfortable shoes and a full day let you see the peninsula without rushing.

The Historic Peninsula compresses Istanbul's thousands of years of layers into a single walk. Planning your accommodation and tour options in the city in advance helps you make the most of your visit.
