Set at the entrance to beautiful bays and natural harbors, lighthouses have prevented ships from running aground for hundreds of years. Sadly, however, many of them have become redundant and been replaced by more effective onboard navigational systems. The ones that remain are, for the most part, automated, and boast more powerful lights and lenses than the beacons used in the past.
As they were designed to be visible, lighthouses often make for very distinctive landmarks: their shapes and colors stand out against the surrounding landscapes. Consequently, they make for some fantastic photo opportunities and are usually set in spectacular spots along rugged coastlines or overlooking wild seas.
