​The mediaeval chapel of St. George the Martyr, situated in close proximity to the San Ġorġ beach in Birżebbuġa, holds the distinction of being the most ancient chapel in the village. The precise year of construction remains unknown; nonetheless, certain sources provide indications of its antiquity.

Evidence of this can be found in one of Matteo Perez d’Aleccio’s murals that portrays the Great Siege of 1565. This particular fresco is housed at the President’s Palace, situated in Valletta.

The construction of the church was accompanied by its connection to Marsaxlokk. The initial pastoral visit was conducted by Monsignor Pietro Duzzina in the year 1575. During that particular period, the chapel was furnished with only a stone altar and a wooden door. The institution lacked a designated priest to oversee its affairs and was devoid of any sources of financial revenue. The commemoration of St. George was observed on the 23rd of April by the conduct of religious services including masses, communion, and vespers.

Throughout the course of the year, a collection was gathered in order to facilitate these festivities. In addition to the designated feast day, the celebration of the mass was regularly observed by individuals who held a deep reverence for St. George, as well as those who were tasked with safeguarding the coastal regions from pirate incursions. During the historical period characterised by the presence of the Knights of St. John, sailors also partook in the observance of mass prior to their departure from the port.

During the year 1621, Bishop Baldasar Cagliares conducted a visit to the Chapel and issued an order for its restoration due to its state of decay. Numerous individuals volunteered their assistance in the repair of the Chapel, culminating in the successful completion of the project in the year 1625. The Chapel was inaugurated by Palmerus Montana J.U.D., and in order to commemorate its significance, a plaque was affixed to the entrance, which remains in place to this day.
