The name "Lucullo's well" is probably due to a nearby reservoir known as "Lucullo's pool", thus extending the misinterpretation about its builder to this archaeological site, too.
The well consists of a system to draw water from an emissary of Lake Paola's Bagnara branch; its mechanism is fairly simple yet effective. It consists of only two structures: a cappuccina-roofed duct to collect the water, and a fountain to drink it. The basin is placed in a 10.30x5.85-metre, barrel-vaulted space.
