Along Ripa Alley have been preserved some portals with fifteenth-century lintels that have survived to the shifts, which have partially shattered the buildings unfortunately.
The portals with lintels are made up of a long horizontal stone (lintel) supported on the abutments formed directly by the wall, some stones, which are laid one on the top of the other or long vertical stones (piers).
Leaving behind the abutments, the beam runs the risk of being broken and, in order to avoid this inconvenience in the openings of a certain width, there was used the arch.
The insertion of the hangers, that is to say jutting shelves, that reduce the width of the empty space under the beam, consented to obtain large openings in an easy and economical way, without using the arch.
The hanger portals, frequent in the town, were spread over at the end of the fourteenth century and were used progressively through a more accurate working and in more refined proportions during the following two centuries.
This portal, located at the left, just before the Alley, has mighty hangers and architraves with a triangular end.
This shape increases the thickness of the stone in the most fragile section and consents to divert laterally the load of the wall above.
Each abutment is made up of two large quadrangular blocks, placed on a stone with L-shaped, which is perfectly embedded in the wall.
The stones are carefully bush-hammered and chamfered.
A little forward, a similar portal has been walled up, obtaining between the hangers a small window. You can find another portal with hangers on the opposite façade.
This gate is located in the mezzanine floor and has abutments made up of large squared stones that are embedded in the wall, which now is partially plastered.
The architrave with a triangular end contains a small cross incised. At the end of the alley, two twin portals made up of simona stone lead to two adjacent vaulted places.
On the central double hanger, which takes the form and the function of the capital, is engraved the date 1469.
