The dramatic stone ruin visible on the headland of Toehead is the Signal Tower, a defensible observation post built around 1805 as part of a chain of coastal defenses against a feared French invasion. Although the square, imposing structure has a castle-like appearance, it was only briefly used for signaling and later adapted as a Coast Guard station before falling into ruin. This scenic coastal area is known for its dramatic cliffs, pristine small beaches, and excellent views across the Atlantic Ocean, making it a popular spot for coastal walks.
