||This paper presents the results of an in-depth study and virtual reconstruction of the Nymphaeum of Veio, in the archaeological zone of Villa Campetti, Rome. The study consisted in analysing the vestiges and enlightening the findings with a thorough literature review about the Nymphaeum itself as well as about contemporary and similar constructions. A digital model was then elaborated, as an attempt to recreate the Nymphaeum of Veio as it may have stood during the Roman period. The Nymphaeum had been decorated with roman frescoes of the III style, now highly deteriorated. The virtual reconstruction intends to reproduce the harmony of volumes, structure and paintings of the chamber. It also helps to better understand its configuration. This kind of reconstruction, based on historical and architectural research, offers great possibilities in the world or architectonic and archaeological heritage, allows the recovery and analysis of spaces otherwise lost forever.
