Frascati Cathedral

The cathedral is built on a Greek cross floorplan, and houses a wooden crucifix of the 11th century from Tusculum,[2] a Madonna (Mysteries of the Rosary) attributed to Domenichino, a relief by Pompeo Ferrucci (1612) representing Jesus handing over the keys to Saint Peter, and a 14th-century Madonna and Child in the Chapel of the Gonfalone, that was retouched by Domenichino.

The interior of the cathedral was destroyed by bombing on 8 September 1943, and so today it appears bare, except for a little chapel off to the right.

In the nave, on the inner side of the façade, there is a white marble funerary monument to Charles Edward Stuart, the Young Pretender, with a memorial tablet.

When he died in 1788, his brother, the Cardinal Duke of York and bishop of Frascati, Henry Benedict Stuart, celebrated his funeral here.

When the body of Charles Stuart was transferred to Saint Peter's Basilica in 1807 after the death of Henry, his heart and praecordia were left here in a small urn, placed under the floor below the funerary monument.
