The Penedo do Guincho is the most singular symbol of the Santa Cruz Beach, formed by an imposing rock structure that stands out from the surrounding cliffs, 30 meters high by 100 meters in circumference, having at its base a recess domed and crossed by the sea.

Its dimension is moving compared to the proportionality if compared with the dimension of the human figure. [+]
