Along the tour, your local guide will take you to the most remarkable Serbian symbol of resilience—the majestic Cathedral of Saint Sava. Modeled after the famous Hagia Sophia in Istanbul, this is the memorial for Saint Sava, the national hero and founder of the Serbian Orthodox Church. After the visit to the cathedral, there will be time to walk along charming old streets and cross Republique Square, the social and cultural heart of Belgrade. Of course, the tour will give guests the opportunity to learn about one of the most famous scientists, inventors and entrepreneurs in history, the Serbian-American Nikola Tesla. Standing next to his museum, you will hear about his eventful life and futuristic ideas.
