The apse above the gallery at the back depicts the universal cult attributed to St George: the angels and saints hail him, the five continents of the world venerate him; all the countries are represented, with pride of place given to Malta and Gozo.

Below the apse you can see the oldest Baroque pipe organ that exists on the island of Gozo. It was built by Sicilian craftsmen in 1781 and, after substantial and expensive restoration by Italian organ builders in 1996, it has now returned to its former splendour. It is not only played during solemn liturgies but it is also sought by various concert organists that come to perform in the Maltese islands.

St George’s Basilica is renowned for its musical tradition. It enjoys the services of a splendid polyphonic choir, the Laudate Pueri, and it is the only church in Malta where Gregorian chant is sung regularly. Such world renowned choirs as the Cappella Sistina and the Canterbury choristers have given concerts of sacred music here, many of them in the context of the annual Victoria International Arts Festival that takes place between mid-June and mid-July.
