Hagia Sophia Grand Mosque
停止: 60 minutes
The Hagia Sophia Mosque in Istanbul is one of the masterpieces of world architecture and a UNESCO World Heritage Site. This 6th-century building contains artistic items and architectural features from the Roman, Byzantine and Ottoman civilizations. It is a must-see in Istanbul, but for that reason, there are long queues which may result with 1-2 hours of waiting time. (If my guests prefer to see the building only from outside in order not to wait in a long queue, an alternative destination can be added)
