Those who like immersing themselves in a foreign culture, religion and historical monuments will definitely want to visit Istanbul, where cultural influences of Europe and Asia intersect. You’ll enjoy visiting dozens of mosques as well as the famous Hagia Sophia and the city’s Kapali Carsi bazaar. Mix relaxing by the sea with sightseeing at, for example, the Side Resort along the Turkish Riviera, which is full of ancient buildings, including an agora, a theater and a Greek temple dedicated to Apollo and Artemis.
