church. The current church, Salem Congregational Church, was built in 1840. The Music Vale Seminary was about a half mile south of the green itself. The town hall, library, recreational fields, and Salem School are all located nearby. A grange and historical society are built around the green. The green has changed little over the past two hundred years, the most changes being in the last two decades. Salem School has undergone many additions since its original construction in 1940. The townspeople in 2003 voted overwhelmingly in a referendum to build a new library, which opened in 2004. The new structure replaced the original library, a tiny structure donated by the Bingham family in 1928, which is now vacant. Also in 2004, construction began on expanded recreational fields.
