Grotta di San Bonaventura

The Grotta di San Bonaventura is cut into the tuff beneath the Belvedere di San Francesco Vecchio at Bagnoregio. An ancient Etruscan tomb became a medieval place of prayer and a focus of Franciscan tradition.

Why it matters

Local tradition identifies the grotto as the place where Francis of Assisi healed the sick child Giovanni Fidanza, who later became Saint Bonaventure. The story connects the landscape of Bagnoregio with the life of a major Franciscan theologian and biographer of Francis.

What to notice

The chamber's excavated rock preserves the modest form of a reused tomb rather than a monumental church. Its position below the Belvedere places the grotto within the setting of San Francesco Vecchio, facing the landscape around Civita and its eroded valleys.

Context and history

The conversion of the ancient burial chamber into a chapel belongs to its medieval history. The Franciscan association gave the space a new devotional meaning, and Bonaventure's subsequent career as minister general and cardinal reinforced his importance to the town. The grotto remains distinct from the saint's commemorative birthplace and other churches dedicated to him.
