Conservaionists are worried that birthday concerts by Elton John in Venice’s St. Mark’s Square could damage the square. “The concerts are part of Sir Elton¹s Red Piano tour and will coincide with the opening of the Venice Biennale. Although the City of Venice has not yet granted official permission for the concerts to take place, tickets for the events are already for sale online. Prices start at 200 euros with the top advertised price set at 1,000 euros. Around 5,000 tickets are available for each event.”
