Overview
Overview
Construction of this church and its adjacent Augustinian monastery was prompted when the started when the order arrived with a putative relic of a spine from the crown of thorns imposed by Jesus during his passion. The Augustinians were banished in 1785 by the Grand Duke of Tuscany, Pietro Leopoldo, although the prior and a small number of monks stayed in town until 1807. The adjacent convent was supposedly built prior to 1349, along with the Santi Giacomo e Giovanni hospital, commissioned by Ottaviano Strenna and using designs by Filippo Belforti. Initially, the church had a single nave, but by 1728 it had the additional aisles added. A further refurbishment occurred in 1885.
