San Giuseppe dei Falegnami (Italian, "St. Joseph of the Carpenters"), also called San Giuseppe a Campo Vaccino ("St. Joseph at the Cowfield", an old name for the Roman Forum), is a Roman Catholic church located next to the Roman Forum in Rome, Italy.
In the 11th-century, the Santi Pietro e Paolo in Carcere (St. Peter & St. Paul in Prison) Church was built here over the Mamertine Prison, which by legend was the incarceration site of Saint Peter and Saint Paul. In 1540, the Congregation of the Carpenters obtained authorization to build a new church here upon the ruins of the Santi Pietro e Paolo in Carcere Church. By 1597, work began on a new (current) church dedicated to the patron saint of carpenters, St. Joseph. The initial architect was Giacomo della Porta. At his death (1602), the work was continued by Giovanni Battista Montano who designed the façade. At his death (1621), the work was continued by his pupil Giovanni Battista Soria. The San Giuseppe dei Falegnami Church was completed in 1663 by Antonio Del Grande (1607-1679), and it was consecrated on November 11, 1663.
