Castel Sant'Angelo, [4]. 09.00 to 19.00, last entry at 18.30, closed on Mondays. - Perhaps the most fascinating building in Rome. The core of the structure began life as the mausoleum of the Emperor Hadrian, built between 135 and 139 AD. Subsequent strongholds built on top of the mausoleum were in turn incorporated into a residence and castle by medieval Popes. The building was used as a prison until 1870, but now houses a museum. Opera buffs will be exhilarated to visit the balcony from which Tosca leaps to her death. Film buffs will recognise as a setting from "Angels and Demons". Euros 8,5, with reductions. Roma Pass accepted.
Palazzo di Giustizia (Palace of Justice).
