The church of Sant'Antonio Abate belongs to an ancient Benedictine complex. Rebuilt at the end of the 15th century, it was considerably altered in 1707.
Inside, it houses two complete cycles of fifteenth century frescoes: the Episodes of the life of Sant’Antonio Abate, by the Maestro of the Dormitio in Terni, and the Stories of the Passion of Christ  in the nuns’ chancel, one of the most impressive examples of the late Gothic narrative of Nicola da Siena.

The sixteen scenes along the walls are divided into two registers, with the exception of the background painting with the great scene of the Calvary. In this pictorial cycle, Nicola da Siena uses a late Gothic language together with the expressive formulae of the Umbrian fourteenth century artists to give a lively, casual interpretation of the story.  The tragic, crude and extremely detailed scenes reflect the need to arouse a strong feeling of pity.

Lastly, the precious, monumental sculpture in wood of Tobias and the Angel was placed in the church presbytery  The sculpture, dating back to the end of the 15th century, was recently attributed to Domenico Indivini, author also of the marquetry in the chancel of the Upper Basilica of St Francis in Assisi.
