Museo Archeologico Regionale Eoliano Luigi Bernabò Brea
This vast, multi-building museum named after its founder is terrific, with an intelligently arranged collection of prehistoric finds—some dating as far back as 4000 BC—from various sites in the archipelago, as well as Greek and Roman artifacts, including an outstanding collection of Greek theatrical masks, and even interesting information on volcanoes. Basic descriptions about the exhibits are provided in English and Italian, though more comprehensive information is in Italian only. That said, there is so much to see, the museum is worth at least a few hours of your time.
