At the top of the hill is the Fort of Mesa Roldan. This is an old fort, about 300 years old, never used for its original purpose of defending against pirates and invaders. After it was built it was realised that the fort was too high for their canon balls and weapons to reach the invaders, and too far away to send couriers with warnings. Today, people go there just for the views, and the park maintenance people use it as a storeroom.
