The area now occupied by the Giusiana Gardens stands on the site of the former Benedictine abbey complex of Santo Stefano, founded in the 11th century and gradually demolished between the 16th and 18th centuries. In 1757, Count Carlo Baldassarre Perrone di San Martino, owner of neighbouring
Palazzo Giusiana, had the remaining structures torn down to expand the garden of his residence, preserving only the bell tower, now known as the
Santo Stefano Tower. The count also commissioned the construction of two small temples, designed by the architect Borra, which no longer survive. == Description ==
