Of medieval origin, the tower was rebuilt in 1732 and then, after it was hit by lightning, the upper part was reconstructed on a design by an engineer from Ancona, Gustavo Bevilacqua, in 1886.
The Galiziano Gate, dating back to the 14th century, was a “double” entrance gate and inside housed the guards who protected the town centre. Its external façade was remade in 1775.
On the opposite side of the surrounding walls, a short distance from the ancient Girola Gate (or Marine Gate, demolished around 1950) lies a little church to the Blessed Virgin, Our Lady of the Snow. Originally it seemed to be a votive chapel erected in the 15th century with a fresco inside depicting the Virgin and Child with Angels which is attributed to Giacomo di Nicola from Recanati and can still be admired today. The church was rebuilt around 1661.
