Built as part of a grand spa complex at the beginning of the 20th century, Sopot’s lighthouse was completed in 1904 and is located right next to the pier entrance. Its design is rather ingenious in that the structure’s primary function was that of a chimney for the boiler that heated the spa waters. The architect came up with the idea of disguising the chimney by constructing a viewing tower and lighthouse around it. A stone spiral staircase takes you up 135 steps to the 25m viewing platform, with a welcoming sofa thoughtfully provided half way up. The viewing platform provides wonderful 360-degree views and photo opportunities of the coast, pier and the roofs of Sopot. The crest over the doorway comprises a mermaid, triton, and the official crest of the city.
