Lighthouses in Iceland are essential for maritime navigation, guiding ships safely along the rugged coastline. With over 100 lighthouses, they are often located on cliffs or islands, providing crucial signals to sailors in the often treacherous waters of the North Atlantic Ocean. Many of these lighthouses, such as Reykjavik's Grótta Lighthouse and Dyrhólaey Lighthouse, are popular tourist attractions. They showcase unique architectural styles and stunning views of the surrounding landscapes, including volcanic mountains and glaciers. These structures not only serve a practical purpose but also reflect Iceland's rich maritime history.
