The Blue Mosque is one of the most popular attractions in Istanbul and a must-see for any visitor to the city.
Whatever time you arrive you are sure to be amazed by the stunning beauty of the architecture and the sheer size of the mosque which was the biggest ever built during the Ottoman Empire.
Built over 400 years ago, the mosque is still an active place of worship for local people so it is best to time your visit to avoid the call to prayer.
The Blue Mosque is easy to reach by public transport from all parts of the city and is conveniently located close to several other popular attractions, such as the Hagia Sophia and the Grand Bazaar.
