Built in 1118, it was indemnified in the Napoleonic period, and totally restructured on the occasion of its reopening to worship in 1821. As a testament to preceding eras, in particular the Medieval era, only the structure on the south side has been reused in the current construction whilst, regarding the old décor, Madonna in glory between the saints Leonardo and Marco Evangelista, by Giovanni Marracci, remains. To increase the patrimony of the Church, other paintings already located in the destroyed oratory of the Gonfalone have become part of it, amongst which the Madonna della Misericordia by Paolo Biancucci and the Madonna dei Miracoli by Gaspare Mannucci, are preserved in the Sacristry. In 1917 a chapel was opened, work of the painter Giuseppe Lunardi, which is the only organic example of Art Nouveau in a church in Lucca, where a Madonna with child by the sculptor Augusto Passaglia is venerated.
