From 17 June to 31 August, a unique opportunity for visitors to admire Piazza del Duomo from the top of the Leaning Tower, exceptionally open until 10.00 p.m., in a fantastic and unprecedented night-time setting.  In addition to the access hours scheduled during the day, it will in fact be possible to visit the famous monument enhanced by the colours of the sunset and the lights of the night, in the silence and peace of the evening hours, when most of the tourist flow has left the Piazza.
