This article analyses Domenico Fontana’s work on the construction of the Capua aqueduct from 1594 onwards. The city
already had an aqueduct built at the beginning of the XVI century which reused the remains of a previous medieval one, but
after almost a century works were required to repair, improve and enlarge the old infrastructure.
Newly discovered documents, hitherto never published, allow us to bring new light on the technical details of the aqueduct
built by Fontana and to appreciate the antiquarian awareness of the Eletti of Capua, i.e. the members of the town’s civic
government, which had commissioned the work to the architect.
