Madonna del Soccorso, Renaissance chapel in Scarlino, Italy.

Madonna del Soccorso is a small rectangular chapel with a single nave, its walls entirely covered in plaster. Angular buttresses run between the ends of the front facade and the side walls, giving the complex a vaguely fortified look. The former chapel now forms the ground floor of a 19th-century residential building on via della Salnitreria.

The chapel was built in the 15th century outside Scarlino's walls near an ancient powder magazine. It remained consecrated until 1829, when construction began and the residential building was erected above it.

The chapel's name, Madonna del Soccorso, refers to the Madonna of Succour, a protective Marian figure. The alternative name Madonna del Giglio came from a Renaissance fresco of that subject once recorded inside. Since the interior is closed to visitors, the name survives mainly in local usage and on maps rather than in anything visible from the street.

The sanctuary is located on the ground floor of a residential building on via della Salnitreria, just near the Porta Pisana gate. Since it is a private location, visitors should check in advance whether access is possible.

After being desecrated in 1829, the sanctuary transformed into a storage space when the residential building was erected above it. This shift shows how a religious structure took on an entirely different purpose.
