The New Fairfield Historical Society is celebrating “50 years of History” this year.  An Open House is being held tomorrow at the Little Red Schoolhouse on Brush Hill Road, across from St. Edward’s Church.  It will take place from 1 to 3pm. The Little Red Schoolhouse is a one-room school that the Historical Society maintains as part of New Fairfield’s living history. This school was originally one of seven built in New Fairfield to educate the town's children. “Open School House” will continue in the months of August and September on the second Sunday of the month.
