The Baltic Sea is home to numerous lighthouses that guide ships safely through its waters. These structures are essential for navigation, especially in areas with rocky coastlines and shallow waters. Many lighthouses in the region are historic, showcasing unique architectural styles and designs that reflect the maritime heritage of the surrounding countries. Countries bordering the Baltic Sea, such as Sweden, Finland, Denmark, and Germany, have maintained these lighthouses for centuries. Some notable examples include the Öland Lighthouse in Sweden and the Helsinki Lighthouse in Finland. These lighthouses not only serve a practical purpose but also attract tourists interested in maritime history.
