The Osservanti branch of the Franciscan order had a decisive influence on L'Aquila. As a result of initiatives by Friar Giovanni da Capistrano and Friar Giacomo della Marca, Lombard masters undertook, in the relatively underdeveloped north-east of the city, an imposing series of buildings centring on the hospital of Saint Salvatore (1446) and the convent and the Basilica of San Bernardino. The construction work was long and difficult, mainly because of the earthquake of 1461, which caused the buildings to collapse, and the translation of the body of San Bernardino did not take place until May 14, 1472. The whole city suffered serious damage on the occasion of the earthquake, and two years went by before repairs on the churches and convents began.
