Santi Vincenzo e Anastasio alle Tre Fontane is a 12th century monastery church.
The church is part of the Abbazia delle Tre Fontane, which is an ancient pilgrimage site. The Abbey of the Three Fountains stands on the site of where St Paul the Apostle is believed to have been martyred.
The interior comprises a nave of nine bays with side aisles. The sanctuary is rectangular, almost square, and the same width as the nave.
Apse
Visitors only have access to the first six bays of the nave. The rest of the church is part of the abbey's enclosure, and is cut off by a wrought-iron screen.
Stained Glass Window
The walls are mostly bare brick and there is little decoration apart from the frescoes of the apostles, which date from the 16th century, and the modern stained glass windows.
