The altarpiece is a recent mosaic copy of Guido Reni’s famous painting of the Archangel which is found in the Capuchin church of Santa Maria della Concezione in Rome. Until 1963, this altar had an older canvas of the warrior saint which had been commissioned by parish priest Paolo Lamagna in 1688. St Michael has enjoyed a very strong cult in this community, as may be seen from the purchase of a very beautiful wooden statue made by Alessandro Farrugia in 1838. The confraternity of shopkeepers named after St Michael was established on this altar in 1809.
