In response to complaints by visitors, a range of new services has been inaugurated at Renzo Piano's music auditorium in Rome. Two ultra-speedy lifts that can carry 11 people each now connect the main foyer to the concert halls. Other improvements include six new toilets, better signposting, braille maps and special indented paths for the disabled. Moreover, technical work has been carried out to improve the halls' acoustics. The company that runs the Parco della Musica reported that from January to July the auditorium had 900,000 visitors.
