The RH/SQ is a Greater Boston hidden gem. Visitors get a fat slice of the untold history of chattel slavery in Medord, Massachusetts. The tour guide Alex not only provided a treasure trove of information but also did so in a way that helped the viewer critically engage the history instead of just giving a catalog of timelines and points. I think this is a very important historic property and though I wish they had more of the original artifacts -- so much has been lost with the property changing hands so many times -- it's a must-visit site if you are looking to move beyond Paul Revere's famous Midnight Ride, the battle of Bunker Hill and all the other played out points of Boston Revolutionary history. It's a good place to learn about the darker side of Boston's history.
