Basilica dei Santi XII Apostoli

This funeral chapel was built in the mid 15th century for Cardinal Bessarione with frescoes attributed to Antoniazzo Romano and Melozzo da Forlì. In the vault you can admire the Choir of Angels and, on the right and left of the chapel, two frescoes that are an important testimony of Renaissance painting.

The church of San Marcello al Corso, dedicated to Pope Marcel I, was built in its present form in 1592 and its concave façade was completed by Carlo Fontana in 1683. The church has existed since the 4th century and is said to have been built on the site of the prison where Pope Marcel I (308-309) died. In the 8th century, Pope Adrian I (772-795) had a church built on the same site, which is now under the modern church.

The Waldensian Evangelical Church of Trevi is a project of Benedetto Andolfi, built in 1883-84. The construction was carried out under the impetus of the Waldensian community recently settled in Rome. The exterior is in neo-Romanesque style and the main entrance of the building consists of a large semicircular arch with a wall almost entirely mosaic of phytomorphic elements, in the centre of which is the portal with a semicircular lunette and a rose window with a marble frame with arches.
