Santissima Trinità dei Pellegrini is a 16th century hospice church. It was designed by Martino Longhi the Elder (1534-91) for the Arciconfraternita dei Pellegrini e dei Convalescenti della Santissima Trinità(Archconfraternity for Pilgrims and Convalescents of the Most Holy Trinity) and consecrated in 1616.
The Archconfraternity was set up in 1548 by San Filippo Neri to look after the sick and poor pilgrims who visited the Eternal City.
St Luke
St Mark
The curved façade was added about a century later to a design by Francesco De Sanctis (1679-1731), the Roman architect who designed the Spanish Steps. The inscription reads: IOES DE RUBEIS PEDEMONTANVS IN SS.TRINITATIS HONOREM F. F. A. MD CCXXIII (Giovanni Rossi from Piedmont had this made in honour of the Holy Trinity in the year 1723). The four stucco statues depict the four evangelists.
Nave
The interior, which was heavily restored in the middle of the 19th century by Antonio Sarti, comprises a nave with three chapels on either side.
High Altar
The high altarpiece depicts The Holy Trinity (1625) and is the work of Guido Reni (1575-1642).
Dome
The pendentives of the dome have frescoes of the four evangelists by Giovanni Battista Ricci (c. 1537-1627).
St Matthew and the Angel by Jacob Cornelisz Cobaert & Pompeo Ferrucci
The right transept altar is dedicated to St Matthew and the statue of the saint is by the Flemish sculptor Jacob Cobaert (c. 1535-1615). This statue was originally commissioned for the altar of the Cappella Contarelliin the church of San Luigi dei Francesi. Cobaert failed to finish the statue on time and Caravaggio was commissioned to step in and paint an image of St Matthew and the Angel.
Cobaert never completed the statue of St Matthew. It was finshed by Pompeo Ferrucci (1566-1637), who also carved the angel.
