Iglesia de San Giovanni in Val di Lago, Ruined church in San Lorenzo Nuovo, Italy
The Iglesia de San Giovanni in Val di Lago is a ruined Renaissance church located just outside the town of San Lorenzo Nuovo, in the Lazio region of Italy. The building has an octagonal floor plan, which sets it apart from most churches of its era.
The church was built between 1563 and 1590, designed by Pietro Tartarino, a student of the architect Alberto da Sangallo. Over the following centuries it gradually fell out of use and into the ruined state it is in today.
The church is dedicated to Saint John the Baptist, and its name reflects that devotion directly. Local tradition holds that a young peasant boy saw an apparition of the saint on this spot, which gave the site a lasting religious meaning for people in the area.
The ruins lie outside the center of San Lorenzo Nuovo and can be reached on foot or by a short drive. Some parts of the remaining walls may be unstable, so it is best to walk carefully and stay on open ground rather than climbing the stonework.
The octagonal shape of the church was not simply an aesthetic choice: in Christian tradition, eight-sided buildings were often associated with resurrection and eternal life. This makes the form particularly fitting for a site connected to a reported saintly vision.
