Neri is buried in the chapel to the left of the choir, which is dedicated to him, in a tomb decorated with mother-of-pearl. Designed by Onorio Longhi in 1600, the first octagonal part of the chapel has a central vault painting of St. Philip by Roncalli, and an altarpiece of "The Virgin Appearing to St Philip Neri" by Guido Reni (now a mosaic copy). In the inner and more removed part of the chapel, Cortona added a lantern to let in more light and the dome was redecorated, perhaps by Ciro Ferri.
