Town walls: south side
Mura della città: lato sud
This is the portion of the walls that gives the clearest view of their overall structure. It has two circular towers at the corners (one of the two being the great tower, independent from the wall), and 3 intermediate towers: a short squared one, and 2 higher semicircular ones between the latter and the corner towers. The northern wall along the current Appian Way, now entirely disappeared, is believed to have had a similar structure.
The walls are built with irregular lime stones and tuffs, organized into rows and glued using a mixture of cobblestone and mortar.
The walls have been partially altered by interventions during the centuries. The top portion of their whole perimeter has been lost: in particular an elevated walk, that surely used to run along the whole system for the watch to be effected; and possibly the battlements.
Le antiche mura [Pro Loco Arpaia]
Most of the information about the town gate (in the page about the norther half of the citadel), as well as the remainder of the walls of Arpaia, comes from this page. Other facts can be found in other pages of the same site.
