MHS is represented on a six-town committee, of which four of the towns have Meeting Houses still standing. Those four Meeting Houses will be open to  tour starting June 1st. The first Sunday of each month, 12-4:00 pm,  June-July-Aug-Sept-Oct-November, the four Meeting Houses will be open to the public with docents there to guide and answer questions. The experience will be augmented with educational banners. Visitors are invited to explore one or all four on any given day of open house.
