Chiesa Evangelica Valdese in Rione Trevi, Protestant church in Rione Trevi, Rome, Italy

The Chiesa Evangelica Valdese in Trevi occupies the ground floor of a larger corner building on via IV Novembre, opposite the Museo delle cere and the INAIL palazzo. Its exterior is neo-Romanesque: a wide round-arched entrance wall covered in plant-motif mosaics, with a semicircular lunette and a marble-framed rose window. The interior is a single rectangular hall in neoclassical style, with a coffered ceiling, Corinthian pilasters, and a semicircular apse holding a wooden pulpit.

The building was erected in 1883 and marks the establishment of the Waldensian Protestant community in Rome following Italian unification. This period allowed religious minorities to organize and construct places of worship in the capital.

The Waldensian community settled in Rome in the second half of the 19th century and built this temple, the city's first Waldensian church; a second one stands in Prati on Piazza Cavour. The land near Piazza Venezia came through the deacon Marquis Giulio Especo y Vera, and Reverend Robert Walter Stewart backed the subscription that funded it.

Access is available during worship services and cultural events held regularly throughout the year. It is helpful to check in advance which activities are scheduled on specific days, as the space alternates between religious and musical programs.

The church is notable for its dual function as a place of Protestant worship and a venue for classical music performances. This blend of religious and artistic purposes is uncommon in Rome and demonstrates how historic buildings adapt to contemporary cultural needs.
