Of ancient foundation, San Giovanni della Pigna is a 17th century confraternity church. The architect was Angelo Torroni, and this is his only church in Rome.
The facade bears the inscription: ARCHICONF PIETATIS CARCERATORVM, the Latin title of the Arciconfraternita della Pietà Verso i Carcerati, which rebuilt the church.
Nave
The interior comprises a single nave of three bays. The side walls have three shallow arched recesses. The main altarpiece depicts St John the Baptist in the Desert by Baldassarre Croce (1558-1628).
High Altar
Three members of the local Porcari family were buried in the church and their tomb slabs were preserved when the old church was demolished. They are now fixed to the walls flanking the entrance.
Tomb Slab of Nicola Porcari
To the right is the tomb slab of Nicola Porcari (d. 1362), which features a pig in the family's coat of arms.
