The Castle of Santa Àgueda (Arabized: Sent Agaiz) is found in the municipality of Ferreries, Minorca. It is situated over an elongated plateau, called Santa Àgueda, 264 m above sea level. It is the third highest point in the island behind Monte Toro (358 m) and S'Esclusa (275 m). The castle is accessed by an ancient Roman road. Next to the castle there was also, until recently, a chapel dedicated to Saint Agatha.
