The village was founded to serve a small defensive watch tower, built at the beginning of the 17th century as a defence against the Barbary pirates for whom Fornells Bay provided the perfect safe haven.
King Charles III of Spain then ordered the partial destruction of the castle and all that is left of the military past of Fornells is the watch tower on the headland, outside the village.
From there to the west Cavallería Cape can be seen, and to the east the massive bulk of Sa Mola, forming the eastern side of the entrance.
The surrounding hills are not high enough to keep out the Tramontane (Tramontana in Catalan), which has shaped the rocks and bent the trees over until the branches almost touch the ground.
Having several small beaches around the bay, the harbour offers a number of aquatic activities for tourists, including boat trips, catamaran excursions, kayaking windsurfing and catamaran tour menorca The annual fiesta de Sant Antoni is held on the fourth weekend in July.
