Sections of a wall, some four courses high in parts and laid on bedrock, were uncovered during trenching works by Enemalta in Strait Street, Valletta, behind Vincenti Buildings.
Denis Darmanin, a student of Baroque architecture and an active volunteer within St Augustine's parish church, strongly believes these courses could possibly have formed part of the foundations of the Order of St John's bakery along what is now Old Bakery Street and extending to Strait Street, designed by Gerolamo Cassar in 1584.
The bakery produced most of the bread and biscuits for Valletta and Floriana and for the garrison and the Order's fleet. The bakery was also used by the French troops during the blockade of 1798 and was heavily guarded by the besieged garrison.
It continued to operate in the 19th century but slowly fell into a state of neglect and eventually closed down.
In the 1930s, the building was bought by architect Ruggier Vincenti, who, after demolishing it, erected a spacious office and residential block which was named after him: Vincenti Buildings.
