San Sisto, Viterbo

In Pinzi's 1894 guide to the principal monuments of Viterbo, he cites the presence of an Ancient Roman altar, used as a baptismal font, that this was originally a pagan temple converted into a church by the 5th or 6th century.

He also noted an altar composed of early Romaneque decorations and the Lombard-style bell-tower to assert the presence of a church here by the 7th to 8th centuries.

[1] However the church we see today, likely dates to after the eighth century, when a neighborhood called Vico Quinzano formed in this area.

The vaults were designed to conceal the old skeletal roofs of the aisles: many altars ripped through the majestic nakedness of the walls and insolent masons covered them with mortar giving in to those who can care not a whit how many paintings, inscriptions and other precious memories existed in that place.The simple facade was reconstructed after the war.

The sole internal altarpiece, dated 1441, is a Madonna and Child, with Saints Sixtus, Felicissima, Lawrence, John the Baptist, Jerome and Nicholas.
