The City of Boston Archaeology Laboratory has put together a display of artifacts found during excavations in the 1990s at the historic Brook Farm  site:
Currently on display at the lab are over 100 artifacts from Brook Farm highlighting the diverse uses of the property, including a 5,000 year old Native American spear point, colonial artifacts, painstakingly reconstructed ceramic serving dishes used by the Brook Farmers, the only physical remains of the massive Phalanstery building, as well as architectural elements and personal items from the Utopian community. The later use of the property is represented by Civil War-era items from Camp Andrew, and toys from an orphanage run out of the Hive building - the heart of Utopian-period community. "These artifacts represent some of the only physical remains of the Brook Farm community and reveal new information about what happened on the propriety before and after the Utopian period" said Joe Bagley, City Archaeologist.
The exhibit, at the lab's office, near Brook Farm at 201 Rivermoor St. , is free, but you'll have to schedule an appointment, Tuesday through Friday, 9 a.m. to 5 p.m. Contact Bagley at 617-635-3850 or firstname.lastname@example.org .
