Caldaccoli Aqueduct

[1] The route started near Corliano (Conserva di Corliano), where an inscription was found (CIL XI 1433) which reports the date of construction of the aqueduct as 92 AD by Lucius Venuleius Montanus Apronianus,[2] patron of the Pisan colony and consul of Attidium (Roman city near Fabriano).

The underground pipeline, consisting of fistulae aquariae in glazed terracotta and supported by a masonry base, descended from the mountain as far as Caldaccoli, here the water was conveyed into a large basin and then channelled onto the arches.

Of the first section of the aqueduct the remains of a pillar with two cut-off arches arranged exactly at right angles.

Subsequently, as described by Giovanni Targioni Tozzetti in the mid- eighteenth century, there were some remains of the pillars in the ground up to the Fosso del Mulino, after which other pillars continued in a straight line and then lost their traces.

It ended at the gates of Pisa just before Porta a Lucca, where there may have been a castellum aquae to distribute the water, a large part of which would have gone to the Roman baths.
