Moors Schoolhouse Site Walking History Tour: November 4, 1:00 PM
The General Field

We are happy to bring back this popular history walking tour. The Moors family was prominent in Groton in the 18th and early 19th centuries, and lent their name to one of the town’s district schoolhouses, which sat on land now stewarded by the Groton Conservation Trust. However, two generations of the family enslaved humans.

As the country grapples with systemic racism, it is important to acknowledge and discuss local threads in the national history of racism and enslavement. Led by local historian Joshua Vollmar, this program will travel from The General Field to the Moors House and Moors School as we seek to bring light to this forgotten piece of Groton history. At the Schoolhouse site, you will learn the history of plantings in the area (see the photo above), and the people who worked the land. This is a walking tour, please dress appropriately. This event is free, but registration is required.

Please visit The GCT events page for details and register here for the walk.

Mark Gerath and Ed McNierney will lead a hike to enjoy the moonlight and to see our landscape in a totally different way. The walk will be about two miles through two of the Town’s conservation areas located on the Chestnut Hills. We will walk up to an open meadow on one of the hills then do a loop past two of the beaver ponds.  Registration is required.
