One of the most famous discos in the capital. Underground and house music, as well as rock and disco music from the 1970s is played, depending on the day of the week. During the summer, Piper becomes "Open-air Piper" situated next to the Circolo Oasi di Pace in Via degli Eugenii. Considered almost as a landmark in Rome due to its thirty-year history, it has been renovated many times and is now a mix of metropolitan and post-modern styles. Saturday brings a mostly gay crowd.
