Madonnella di San Marco is a small late 17th century devotional chapel which was dismantled and inserted into the ground floor of the Palazzo Venezia, a 15th century edifice, in the 20th century. The separate entrance doorway is on the right hand side of the façade of the palazzo on the west side of the Piazza Venezia.

The chapel is counted as attached to the basilica of San Marco, with the same postal address of Piazza di San Marco 48. However, its separate entrance and own history justifies its being given its own page on this Wiki.


Arco di San MarcoEdit

The icon venerated in the chapel used to be in a nearby street known as Via dell'Arco di San Marco, under the archway which gave the street its name.

Before the massive alterations to the Piazza Venezia beginning in the late 19th century, the piazza was much smaller than it is now. The eastern frontage of the Palazzo Venezia took up the entire west side, while the southern side was occupied by the Palazzetto Venezia which joined onto the Palazzo at its south-east corner. The church of San Marco occupied the north side of its own piazza to the west, with the Palazzetto forming the east side.

The Via delle Botteghe Oscure ran into the Piazza di San Marco at its south-west corner. The Via dell'Arco di San Marco exited from the south-east corner, ran along the south side of the Palazzetto and became the Luogo della Ripresa dei Barberi before ending up at Santa Maria di Loreto. The archway over it carried an elevated walkway which used to connect the Palazzo Venezia with the Campodoglio.

In 1654, the canons of San Marco commissioned Bernardino Gagliardi to paint a street icon of Our Lady, and installed it under the archway.

Miracle, and foundation of chapelEdit

The icon attracted serious devotion after a miracle was reported in 1668. A young nobleman was mugged by an assailant who tried to stab him with a dagger, but the dagger bent as if it were made of plastic and the attacker fled.

Thirty years after this, funds had been collected to furnish a chapel for the icon. The project had been sponsored by the ambassador from Venice, one of the great Barbarigo clan of Venice, and much of the money came from the local Ruspoli family. The location chosen was in the Palazzetto, which was arcaded on four sides around a central formal garden. The little chapel was in the north-west corner of the arcade, and was accessed from a doorway in the frontage on the south side of the Piazza Venezia.


In the early 20th century, it was decided to improve the layout of the area around the new Il VIttoriano and to enlarge the Piazza Venezia as a traffic hub. One major intervention was the demolition of the Palazzetto and its re-building on the west side of the Piazza di San Marco. However, the chapel was not moved there with it. Its interior was dismantled, and re-erected in a little room in the north-east corner of the Palazzo Venezia. It was then accessed by its own door from the piazza.


The chapel has been accessible to devotional visits ever since. However its profile was raised in 1957 when Mother Maria Oliva Bonaldo, foundress of the congregation of the Daughters of the Church, established a small convent attached to San Marco. This is the Casa Speculum Iustitiae ("House of the Mirror of Righteousness"), and the sisters resident there have made the chapel a centre of Eucharistic devotion. Another adjacent room in the Palazzo was taken over, and used as a chapel for Exposition of the Blessed Sacrament.


The doorcase is marble, with simple linear molding and with a coat of arms affixed to the wall above. This is the only indication that there is a chapel here.

Street entrance to the chapel.


Icon chapelEdit

On entering, you find yourself in the tiny original chapel.

To the left is the ornate Baroque altar by Giovan Battista Contini, in polychrome marble dominated by red, yellow and green. This has an unusual form, since it is not an aedicule but more resembles a funerary monument. A coved (concave) entablature in verde antico is on top of the actual altar, and at the ends of this are two angels in white marble who are adoring the icon after which the chapel is named. The icon itself is enshrined in a coved trapezoidal slab with incurved sides, which is in red marble with a verde antico border. On top is an omega cornice (Ω), on which a pair of putti are holding a large bronze crown. The sides of the panel have swags and curlicues in yellow SIena marble, and the same stone is used for the omega cornice and the cornice of the entablature below.

The sculptures of the angels, putti and the winged putto's heads on the face of the slab are by Filippo Carcani.

Our Lady in the icon is shown suckling the Christ-Child, and above is a plaque giving the title Maria Mater Gratiarum (Mary, Mother of Graces). 

A fresco of the Holy Family travelling to Egypt is to the right of the altar. It is attributed to Alessandro Algardi.

Above, the cross-vaulted ceiling of the chapel is almost completely covered in gilded stucco decoration containing tondi with reliefs, and is very impressive.

Exposition chapelEdit

The exposition chapel is through the doorway opposite the entrance. It is very plain, with whitewashed walls and ceiling. The only remnants of the former decoration of this palazzo room are narrow marble Corinthian pilasters embedded in the side walls, looking rather lost.

Access and liturgyEdit

The chapel is a popular centre of Eucharistic adoration, which has rather taken attention away from the icon. Also it has become the ferial chapel for the parish of San Marco, which now celebrates its weekday Masses here.

Mass is celebrated (parish website, June 2018):

Weekdays 7:30 (not August) and 19:30 (not Saturdays).

The Blessed Sacrament is exposed for veneration after the 7:30 Mass to 12:30, then 16:00 to 19:00, Monday to Saturday.

The sisters celebrate the Divine Office here Monday to Friday, with Lauds at 7:00, Sext at 12:00 and Vespers at 19:00. On Sundays and Solemnities, Vespers is at 18:00.

Visitors are asked to show respect, and not to take photos.
