Volunteers from Fondo Ambiente Italiano (FAI) are conducting free guided tours of Teatro Argentina on Saturday 7 February from 10.00-16.00 (last entry 15.30).

The tour includes the building's labyrinthine rooms, tracing its history from mediaeval times until the 18th-century when Duke Giuseppe Sforza Cesarini converted it into the theatre that still stands today.

The cosa FAI oggi tour is part of a series designed to highlight little-known archaeological sites in Rome and is the result of collaboration between FAI and the city's cultural authorities.

Similar to Britain’s National Trust, FAI works to preserve and promote Italy’s cultural heritage through education, restoration and annual open days, known in particular for its hugely popular annual Spring Day.
