Celebrate Pelham’s 275th by learning about Shays’ Rebellion from UMass Professor of History Leonard Richards, author of “Shays’s Rebellion: The American Revolution’s Final Battle.” In the historic Town Hall, Richards will highlight the role of Pelham residents in that famed controversy. Following Richards’ presentation, a ribbon-cutting ceremony at the Museum next door will inaugurate the new interactive Conkey Tavern area where visitors can role-play historic tavern discussions and 18^th century Pelham life.
