The Melita Foundation contributed to the conservation of the Great Siege wall painting by Matteo Perez D’Aleccio at the Grand Master’s Palace in Valletta. Created between 1575 and 1581, these paintings are the first monumental artworks commissioned by the Order of St John. They offer the most accurate depiction of the Siege and are vital to preserving Malta’s historical identity for future generations. The project, undertaken by the University of Malta’s Department of Conservation of Built Heritage and Heritage Malta (Research, Innovation, and Development Trust), worked to stabilise and clean the paintings, with restoration completed in 2023.
