Francesco Antonio Picchiati (1616-1694). Italian architect from Naples. Son of architect Bartolommeo Picchiati. Francesco Antonio Picchiati is known primarily for three projects in Naples:
•the chapel for the building at Monte della Misericordia in Naples, which contains Caravaggio's The Seven Works of Mercy;
•the Spire of San Domenico to a design by Cosimo Fanzago. Picchiati was so intent on preserving and cataloging remnants of the original Greco-Roman city beneath the contruction site that work on the spire, itself, was eventually suspended and not until many years later;
•the convent of Santa Croce di Luca, begun in 1643. The convent stood at the extreme western end of the old historic city. It was demolished in 1900 to make room for the new Polyclinic hospital; a small section was left standing as a historical marker.
