The transept to the left hand side of the main altar has a beautiful altar dedicated to the Holy Souls. The huge canvas is the second Preti in St George’s Basilica, and it represents Our Lady of Graces with the souls in Purgatory. The donors of the painting are seen on both sides shedding water to alleviate the souls’ suffering. Designed by Francesco V. Zahra in 1759 and crafted by the Durante family of marble-makers, the altar had been commissioned by its procurator, Can. Gian Pietro Francesco Agius de Soldanis, famous as the author of the first written history of Gozo. It rises above the underground crypt that was unfortunately destroyed in the early 1930s and lacks important decorations that were removed during the puritanical Alizarin period of the late 1780s, a spiritualist movement that sought a Catholic return to the original purity of the faith and destroyed many carvings in stone and marble in this church.

The vault above this altar depicts an episode in the martyrdom of St George, while the apse evokes the 1429 siege of the city of Mdina, then Malta’s capital, when according to contemporary chroniclers, St Paul, St George and St Agatha appeared above the walls of the city and aided the embattled islanders to repel the Moors seeking to conquer the island.

The statue of Our Lady of Sorrows, which also stands in this chapel, was made by Michael Camilleri Cauchi in papier-mâché in 1982, and donated to the basilica by Bishop Mgr Nicholas J. Cauchi, founder of the Chapter.

A wooden statue of Our Lady of Fatima, brought from Portugal in 1950, stands on the altar.
