The chapel was built in 1535 on land owned by the Cathedral chapter through the initiatives of Paolo Pellegrino. In return an honorary canon of the cathedral was obliged to bear the expenses for the celebration of the feast of the saint and to provide alms for the poor on the feast day, a custom that persisted until WWII. The expenses for the construction of the church were seen to by the cathedral chapter with the chapel being administered by the cathedral Precentor. After WWII the chapel was neglected and disused. It was only recently that the chapel was restored and used for worship.
