Yes, it's a museum, but not a walk-around-reading-plaques-in- front-of -artifacts kind of museum. Instead, you are placed INSIDE of history. Knowledgeable and entertaining tour guides take you through this event in history, helping you envision exactly what happened and what it was like. It's not cheap, but your ticket is free if you are using the Town Trolley.
