South of the town centre, past the Porta di San Pietro, this 10th-century basilica's interior is an incredible mix of gilt and marble, and contains a Pietà (a painting of the dead Christ supported by the Madonna) by Perugino. For a glimpse into gardens past, take a stroll or picnic at the serene Orto Medievale gardens, behind the basilica.
During the medieval period, monasteries often created gardens reminiscent of the Garden of Eden and biblical stories, with plants that symbolised myths and sacred stories. Numbered locations through this garden include the Cosmic Tree, symbolising the forefather of all trees; the Tree of Light and Knowledge; and the Tree of Good and Evil.
