San Giovanni Battista del Gonfalone, Viterbo

San Giovanni Battista del Gonfalone (St John the Baptist of the Banner) is a Baroque architecture, Roman Catholic oratory (chapel or small church for a confraternity) located on #11 Via Cardinal La Fontaine in Viterbo, region of Lazio, Italy.

Among its aims was to collect funds to pay the ransoms of the Christian prisoners being held by Muslims, as well as providing a dowry for two decent orphan girls.

In 1664, the confraternity purchased this site, and commissioned the design of a new oratory church from the architect Giovanni Maria Baratta.

The St John the Baptist before Herod (1756) in the lunette of the main altar was painted by a local artist, Anton Angelo Falaschi.

The yellow veined marble frontal with green and red border displays the symbol of the Confraternity in its centre.

On the walls above these, painted by Pietro Piazza and his compatriot Giuseppe Rosa are a series of monochrome scenes portraying episodes from the life of the Baptist.
