Supported by two frosted shelves and decorated along the surface by a wreath of wreath-shaped wreaths, emerging from the mouths of two fantastic animals at the ends.
On the decoration is a Gothic inscription bearing the name of the author: MAGI [STER] A [N] DREAS DE PIPERNO ME FECIT. It is an original sculptor from Priverno, famous only for making this portal, probably in the first half of the 14th century.
