The Church of St. Peter Martyr, with entrance on Piazzetta Ruggiero Bonghi in Corso Umberto I, represents the physical boundary of the disappeared district of San Giuseppe dei Fiorentini, today incorporated by the Art Nouveau architecture of the fascist renovation, in the newly founded area of the district of San Giuseppe-Carity.
Founded in 1294, dedicated to San Pietro Martire da Verona who died in 1252 and initially completed in the first half of the 15th century, today it is located in front of the south entrance of via di Mezzocannone.It was founded in 1294 by the Angevins who, once completed in 1347, donated it to the Dominicans. In the same year the church was enriched with the marble portal made by Giovanni Capuano. Other works were necessary in the XV century, because of a fire in 1423 and of an earthquake in 1456, and the structure underwent a transformation approaching a more Renaissance style.
The church of San Pietro Martire therefore presents itself today with dome and tribune and a single nave, once cluttered for the most part by a choir moved in 1551 behind the high altar by Prior Ambrogio da Bagnoli of the Salvi family.
