Picture a sentinel in an old stone watchtower, perched high up on the cliffs of Punta de la Mona. He can see for miles out to sea and along the coastline, with mountainous lands jetting right into the sea. He is there protecting the castles and the nearby villages. There’s nothing but the rocky cliffs with the sea crashing below. He has means to communicate with the neighboring watchtowers along the coast, via light signals. This was the life of a watchman back in the 1700’s.
