San Giovanni Calabria a Valle della Storta is a 20th century public dependent chapel of the parish of Sacri Cuori di Gesù e Maria di Porto Santa Rufina and is at Via Sabatino Lopez 2, which is on the eastern edge of the surburb of Torrione Cerquetta north of La Storta on the Via Cassia. This is in the La Storta zone.
The patron, St John Calabria, was a holy priest of Verona who founded two religious congregations and who died in 1944.
This chapel is in the municipality of Rome, but belongs to the diocese of Porto Santa Rufina.
It occupies part of the ground floor of a shabby three-storey apartment block, and is very easy to overlook. The entrance is in one end of the block.
Mass is celebrated (2016) at 17:00 on Thursdays and 9:00 on Sundays, but check the parish web-page here.
