The Grand Master asked the European kings and princes for help, receiving a lot of assistance due to the increased fame of the Order after their victory in the Great Siege. Pope Pius V sent his military architect, Francesco Laparelli, to design the new city, while Philip II of Spain sent substantial monetary aid. The foundation stone of the city was laid by Grand Master de Valette on 28 March 1566. He placed the first stone in what later became Our Lady of Victories Church.
