Oratorio dell'Angelo Custode is an 18th century Baroque oratory at Piazza Poli 11 on the Via del Tritone, which is in the rione Trevi. Pictures of the church at Wikimedia Commons are here.

Name and statusEdit

This edifice used to be called Oratorio del Santissimo Sacramento al Tritone. However recently it has been renamed Oratorio dell'Angelo Custode, in reference of the lost church of Angelo Custode which used to be nearby. Hence, the dedication is now to the Guardian Angel

The old name is still used on the diocesan web-page.


The edifice was built as a headquarters of the Archconfraternity of the Blessed Sacrament (Arciconfraternita del Santissimo Sacramento) of the parish of Santa Maria in Via.

Construction started in 1576 during the pontificate of Gregory XIII (15721585), but the building was not completed until 1596. In 1681, Carlo Rainaldi oversaw a restoration.

The oratory was completely rebuilt by Domenico Gregorini between 1726 and 1730, during the pontificate of Benedict XIII (17241730) and under the patronage of Cardinal Pietro Ottoboni.

There was another restoration by Tito Armellini, father of the famous Roman church historian, in 1867.

The western part of the present Via del Tritone was built as a completely new street at the end of the 19th century, and this entailed the demolition of the building abutting the church on its north side. As a result, the right hand side wall was re-faced in 1897.

The edifice is now a centre of devotion to the Guardian Angels, and is a well-used place for private prayer.


Layout and fabricEdit

The layout is a simple rectangle, with a little rectangular apse. Although the interior is domed, the dome is false. The roof is actually flat, with a parapet and a large central elliptical lantern which is invisible from the ground. There is a campanile or bellcote with a tall open arch and a triangular pediment, and this is on the left hand side wall just behind the façade.


The two-storey façade used to be described as being by Carlo Rainaldi in the style of Borromini, and completed in 1681. It is now regarded as being part of the 18th century rebuilding by Gregorini.

The profile is wavy, with a convex central element flanked by two concave outer elements, all rendered in white. Above the entrance are two winged heads of putti below a cornice with a low ogee curve, and the entrance is flanked by two pairs of Corinthian columns with decorated Ionic capitals and supporting two halves of a broken and separated segmental pediment with entablature which intrudes onto the second storey. On the pediment halves are two reclining statues representing the virtues Faith and Hope, and these are by Paolo Benaglia.

The plinths of these columns are angled inwards, following the concavity of the outer parts of the façade, so that these pediment halves stand proud of the vertical face of the façade. The first storey is framed by a pair of rectangular pilasters in the same style.

The second storey has a round-headed central window topped by a winged putto’s head below a complex ogee curve, and having a pair of columns flanked by a pair of pilasters. The columns are in grey marble. Either side of the window are two pairs of conjointed rectangular pilasters with capitals, supporting a fanciful pediment formed of two halves of a segmental pediment joined onto a central triangular one. The outer elements of the second storey have capsule-shaped vertical windows (the shape is formed from a rectangle with a semicircle at either end), and these have short sections of balustrade below them. Finally, there is another pair of pilasters at the corners matching those of the first storey, and above these is a pair of flaming urn finials.


The interior plan is a chamfered rectangle (the corners are rounded), and is dominated by the dome. This sits on an entablature supported by ribbed Composite pilasters in light grey with gilded capitals.

The wall and dome surfaces are richly decorated, with frescoes by Luigi Martinori dating from the 1867 restoration. There is a pair of cantoria, or cantilevered opera-boxes for solo musical performers, flanking the apse.

The altar is in a little apse, amounting to an arched niche. The large altarpiece depicting the Holy Family is by Francesco Trevisani, and dates from the 18th century rebuilding. This artist was a favourite of Cardinal Ottoboni.


The opening times are generous, and the Confraternity should be commended for them. They are: 7:30 to 23:00, closed Monday.


Mass is celebrated:

Sundays, 9:30, 11:30, 12:00 (unofficial source).
