San Giuseppe dei Falegnami

 
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 in the Forum in Rome, Italy. 
In 1540, the Congregation of the Carpenters had leased the former church of "San Pietro in Carcere" which was located over the Mamertine Prison, which by legend had held Saint Peter and Saint Paul. By 1597 work began on the new church, dedicated to the patron saint of Carpenters, St. Joseph. The initial architect was Giacomo della Porta. Work continued after 1602 under the direction of Giovanni Battista Montano, who designed the facade, and at his death (1621) by his pupil Giovanni Battista Soria. The church was completed in 1663 by Antonio Del Grande. The church was restored in 1886 with the construction of a new apse. 
In the 1930s, the facade was raised above the floor to allow direct access to the prison below. The interior has a nave with two side chapels that were decorated in the nineteenth century. Among the paintings is a "Nativity" (1651) by Carlo Maratta. Next to the church is an oratory, with a wooden ceiling, and the 16th-century Chapel of the Crucifix, placed between the church floor and the ceiling below the Mamertine Prison.
On 18 February 2012, it became a titular church, receiving its first Cardinal-Deacon.
On 30 August 2018, there was a partial collapse of the church's roof.
