The 17th century church of San Nicola da Tolentino agli Orti di Sallustiano (St Nicholas of Tolentino at the Gardens of Sallust) is dedicated to St Nicholas of Tolentino, a 13th century Augustinian friar.
St Nicholas of Tolentino (c. 1246-1305) is known as the patron of Holy Souls and is particularly invoked as an advocate for the souls in Purgatory. He was canonised by Pope Eugenius IV (r. 1431-47) on June 6th 1446. His feast day is September 10th.
Nave
The interior comprises a nave with three chapels on either side, a transept with a central dome and a shallow rectangular apse.
High Altar
The high altar was designed by Alessandro Algardi (1598-1655). The front columns support a split pediment, on which recline two angels by Giovanni Maria Baratta (c.1627 - c.1680). The bas-relief of God the Father is by Ercole Ferrata (1620-86).
High Altar
The altarpiece is by two sculptors. The Virgin and Child, St Augustine and St Monica are by Ercole Ferrata, while St Nicholas is by Domenico Guidi (1625-1701).
Dome
The pendentives of the dome are decorated with four female figures symbolizing the four fundamental virtues of the Augustinian Order: Chastity, Humility, Poverty and Obedience. They were executed by Pietro Paolo Ubaldini in 1643. The fresco in the cupola depicts The Apotheosis of St Nicholas of Tolentino by Giovanni Coli and Filippo Gherardi.
