The Architect

The great structure was designed by the maltese architect Gerolamo Cassar (1520-c.1586).He was in his 50's and had ,it has been speculated ,travelled abroad. He was able to take responsibility for much of the earlier building work which characterises Valletta. Cassar was not only a trained military enginier , but he had also sevioured the latest roman trends of palatial architecture .He trained under Francesco Laparelli da Cortona, the Italian military engineer sent by Pope Pius V after the Great Siege of Malta (1565) to plan Valletta’s fortifications. this made him eminently siutably to take on the task of planning and designing the principle auberges and palazzi.

He built the Grand Master's Palace , seven Auberges ,The Sacra infermeria , the Order's Bakery and Verdala Castle and more . It is evident that Cassar had seen some of Michelangelos Architectural works probabely including plans and models there are great similarities between the facade of st john's and the proposed facade of St Lorenzo in Florence . Also ,aspects of the interior
of the Medici chaples in the same city match up well with st john's exterior .This was obserbed in recent years by a maltese architect and historian the late leonard mahony . He wrote ;Cassar's knolage of the exact measures of mechelangelo's works is probabely deu to Laparelli who was Michelangelo's trusted assistant on the fabric of St. Peter's in Rome .

Major Works

Cassar was the chief Maltese architect responsible for much of Valletta’s civic and religious architecture in the late 16th century.

His works include:

St. John’s Co-Cathedral (1572–1577)

  • Commissioned by Grand Master **Jean de la Cassière.
  • Built in Mannerist style: fortress-like exterior, simple rectangular plan, and barrel-vaulted nave.
  • Intended to reflect the austere spirituality of the Knights.
  • Interior remained plain until Mattia Preti’s Baroque embellishments in the 1660s.
  • The Grandmaster’s Palace (Valletta)

  • Served as the residence of the Grand Master.
  • Auberges (lodges) of the Knights’ Langues

    Cassar designed or oversaw most of them, including:

  • Auberge de Castille
  • Auberge d’Italie
  • Auberge de Provence
  • Auberge d’Aragon
  • Each served as headquarters for a “langue” (national group) of knights.
  • Other Valletta landmarks

  • Several churches, including St. James Cavalier**, Our Lady of Victories, and chapels.
  • Public buildings, streets, and squares that gave Valletta its grid plan.
