Villa di Plinio, Chiesa della is a small ruined church hidden away in the extensive pine woods next to the ancient Via Severiana, due east of Lido de Castel Fusano. The nearest named road is the Viale della Villa di Plinio.
The surviving foundations, which have been excavated and lie exposed, show a little rectangular building with a semi-circular apse. In front of the apse are the longitudinal stone edges of a shrine or tomb. The history of this church seems to be undocumented, and any link with the nearby Villa di Plinio is unprovable. It is not easy to find, being completely surrounded by scrubby woodland. A track leads to it from the north-east of the villa ruins.
