To a sailor the lighthouse is a symbol of hope – a sanctuary at sea. In Leningradskaya Oblast the guiding light of these towering structures has been illuminating the waters for more than 300 years, saving human lives on a daily basis. Each one of these lighthouses is unique in its own way and has its own story, which is not always merely connected to the sea and its ships. Nowadays however, with new navigation technology, do we really need these lighthouses and do lighthouse keepers even still exist? RTG TV presenter Alexander Uvarov discovered the answers to these questions and more while on a fascinating water adventure to the lighthouses of Lake Ladoga and the Finnish Gulf.
