Civic Museum of the Middle Ages
Part of Musei Civici d'Arte Antica.
The palace was built between 1244-1246 as an extension of the nearby Palazzo del Podestà. It takes its name from Enzio of Sardinia, Frederick II's son, who was prisoner here from 1249 until his death in 1272. The current Gothic appearance dates from the restoration of 1905 due to Alfonso Rubbiani.
Roman Excavations of the "Stock Exchange" Library
A compact basement-level field of ruins from Bologna's past, from 2nd-century BCE Roman roads and buildings, to a 16th-century CE cistern. Metal walkways take you on a 100-m course over and around the ruins. But this thoughtful display is all the more interesting for its location: under a 19th-century stock exchange hall ("salaborsa"), which has been converted to a 21st-century library. Enjoy this airy, pleasant room on your way down to the ruins. A colourful flyer gives context in English and Italian. An easy excursion right on Piazza Maggiore.
