The architectural landscape of Malta was fundamentally reshaped by Girolamo Cassar, a master builder who emerged from the defensive necessities of the Great Siege of 1565. As the resident engineer of the Order of St. John, he transitioned from a military tactician into the primary architect behind the construction and formalization of the new capital, Valletta.
Military Origins and Training
Born around 1520 in Birgu, Cassar began his professional life as a capomastro, or master builder. His early technical education was overseen by Evangelista Menga, the resident engineer of the Order. His expertise was refined under the pressure of active combat, specifically during the Battle of Djerba and the subsequent Great Siege of Malta. During these campaigns, he managed the repair of fortifications damaged by Ottoman assaults, gaining firsthand knowledge of structural defense and logistics.

In 1566, the Order commissioned the creation of a new capital. Cassar initially served as an assistant to the Italian military engineer Francesco Laparelli, contributing to the development of the city's grid plan and defensive perimeter. Following Laparelli’s departure from the island in late 1569, Cassar assumed full control of the city's architectural direction. His influence over the capital was comprehensive, as he was responsible for designing the Conventual Church of St. John, the Grandmaster’s Palace, and the seven original auberges.
Architectural Style and Travel
In 1569, the Order formally recognized Cassar’s contributions, granting him membership and providing a passport for travel to Italy. During his time in cities including Naples, Rome, and Lucca, he observed the Mannerist style. Upon his return, he integrated these aesthetic elements into his public, religious, and private commissions. Beyond the walls of Valletta, he also executed significant projects such as the Verdala Palace in Buskett and the initial design of the Sacra Infermeria.
Personal Life and Succession
Cassar’s private life was marked by complex legal and personal arrangements. He eventually married Matthia Cassia, with whom he had five children, including his eldest son, Vittorio. Vittorio followed his father into the profession, eventually succeeding him as the resident engineer for the Order. Despite his professional status and the maintenance of a household that included at least two enslaved persons, Cassar maintained an often litigious relationship with his family, including the formal disinheritance of his son born out of wedlock, Gio Domenico.
