Formerly the chapel of the School of St. Francis, whose crest is still visible over the arch, it contains a 14th century monument to Arnoldo d' Este and a Gothic monument to the Florentine ambassador Duccio Alberti.
On the left-hand pillar of the chapel are an epigraph commemorating the consecration of the Basilica ( 27th May 1492 ) and a small 13th century bas relief of the Dead Christ.
The altar is a recent work by the sculptor Vincenzo Cadorin ( early 20th century ), with fine gildings by the brothers Michieli of the Frari.
