Santa Maria Scala Coeli

This is one of three churches affiliated with the Trappist monastery, and is located on a small lane, Via delle Tre Fontane, inside the abbey complex.

Subsequently, the present church was designed by Giacomo della Porta under the patronage of Cardinal Pietro Aldobrandini.

The church presbytery contains a mosaic by Francesco Zucca made after designs of Giovanni della Vecchia.

[2] An old tradition claims that 10,000 Christian slaves who died while building the Baths of Diocletian are buried in the church's crypt, and are venerated as St Zeno[3] and Companions.

The vision was of the souls in purgatory he was praying for ascending to heaven by a ladder — the Scala Coeli, leading to the church's suffix.
