It is the first and the only Mosque in Rome, located at the foot of the hill. It was erected in 1984-93, and designed by Paolo Portoghesi, Vittorio Gigliotti and Sami Monsawi. The mosque, that can hold up to 3000 people and is the largest in Europe, was financed by some 24 Arab countries. There is also a cultural center and library here.
