For over 100 years the Arena in Verona has formally hosted opera, with Aida being at the forefront of the entertainment on show.  The huge Verona Arena, which is a first century Roman amphitheatre, is at the centre of activities in this old medieval town.  The Arena originally hosted 30,000 people every night during the summer but, even in Italy, health and safety gradually reduced this sum to 25,000, 20,000 and today 15,000 maximum capacity.
