Monte di Pietà is the large well-maintained (it's owned
by the Bank of Naples!) building on the south side
of via San Biagio dei Librai near the
intersection of via San Gregorio Armeno (#25 on this map). The church at
the back of the courtyard that you see as you peer
through the large portal is properly called the
Chapel of the Monte di Pietà. The entire structure has to do with the
institution in Italy of church-run non-profit pawn
houses that had started to open throughout Italy in
the mid-1400s in order to combat usury. (See this link for
further information on the origins of pawn houses and
public banks in Naples.)
The Monte di Pietà was, indeed, one of the
first such "pawn houses" in Naples, founded in 1539.
The original institution was in the Palazzo Carafa
d'Andrea some blocks farther to west, still in
the historic center of town. The Monte acquired new
property, the current location, in 1597, purchasing
the residence of Girolamo Caraffa. (Caraffa —also
spelled Carafa— is a family of Neapolitan nobility
going back to the 11th century and with a subsequent
genealogy of noblemen, military and clergy.) The
original building on the site was demolished and a new
one put up, the one we see today, by Giovan Battista Cavagna,
the architect also responsible for a number of other
works in Naples, including the facade of the grand
church and monastery of San
Gregorio Armeno around the corner from the
Monte di Pietà.
The chapel "annex" of the pawn brokerage was
finished in 1605 and was the product of the combined
sculpting and painting genius of Michelangelo Naccherino,
Pietro Bernini (1562-1629), father of the better known Gian Lorenzo
Bernini), Belisario
Corenzio, and Fabrizio Santafede.
During Masaniello's
Revolt in 1647, the building was spared the
ravages of the violence through a timely intervention
on the part of Giulio Genoino, an elderly priest
widely believed to be the "brains" behind the revolt.
There was, however, a mysterious fire in 1786 that did
a great deal of damage to the premises, by that time
gone from pawn brokerage to public bank. (The building
still houses an important branch of the Bank of
Naples.) The chapel, however, was not damaged. The
chapel is a jewel of artwork from the Neapolitan
Baroque of the 1600s. It is decorated in gilt stucco
and has a majolica tile floor; other than the artists
mentioned above, there are works by Ippolito Borghese,
Giuseppe Bonito, the tomb of cardinal Ottavio
Acquaviva by Cosimo Fanzago
and, from a later period, portraits of Charles III of Bourbon
and his queen consort, Maria Amalia, the first Bourbon
royal family of the Kingdom of Naples.
