An octagonal lantern tower is a structure characterized by its eight-sided shape, often found on lighthouses or as part of architectural designs. These towers typically feature a lantern at the top, which houses a light source to guide ships or provide illumination. The octagonal design allows for a unique aesthetic and can enhance stability. The lantern tower is often constructed using materials like stone, brick, or metal, depending on its purpose and location. In maritime contexts, such towers are crucial for navigation, while in other settings, they may serve decorative or functional roles in buildings or parks.
