San Carlo ai Catinari. San Carlo ai Catinari, also called Santi Biagio e Carlo ai Catinari is an early-Baroque style church in Rome, Italy.
It is located on Piazza Benedetto Cairoli, 117 just off the corner of Via Arenula and Via dei Falegnami, a few blocks south of the church of Sant'Andrea della Valle. The attribute ai Catinari refers to the presence, at the time of its construction, of the many makers of wooden basins who worked in the area.
The church was commissioned by the Order of the Barnabites and funded by the Milanese community in Rome to honour their fellow Milanese St. Charles Borromeo. It is one of at least three Roman churches dedicated to him, including San Carlo al Corso and San Carlo alle Quattro Fontane.
The Barnabites in Milan had had close ties to Cardinal Borromeo. He had helped draft the order's constitutions, and they had assisted in ministering during the plague of 1576.
When their little church of San Biagio all'Anello in Rome had become too small, they purchased adjoining land and constructed a larger one. Borromeo had been canonized in November 1610. Construction began in September 1611 making this the first church in Rome dedicated to him. In 1618 S. Biagio's was razed, and the new name formally conferred on the parish. The main design was by Rosato Rosati between 1612 and 1620, at the private expense of Cardinal Giambattista Leni. The travertine facade was designed by Gi
