2017 is a significant year for three of Worcester’s organizations.  At the Tower Hill Botanic Garden library from January through June, view historic material on display from the Worcester Agricultural Society (founded 1817), the Worcester County Mechanics Association (founded 1842), and the Worcester County Horticultural Society (also founded 1842), that show the connections between all three.  Free with admission.  For more information visit www.towerhillbg.org.
