Londonderry is the best of both worlds, a tight knit suburban community, but also an economic center, sitting just outside of Manchester, and 45 minutes outside of Boston, an area called New Hampshire’s “Enterprise Corridor”.  Even though much of the original Londonderry territory included various surrounding towns such as Derry, Londonderry is still the fourth largest town in NH.

Londonderry’s history is mostly agricultural based with a large concentration of family-owned apple orchards and farms. Since its incorporation, it has developed in to a expanding community with a mix of a traditional New England values with a growing business and industrial economy. A well rounded community, Londonderry is not only home to Stonyfield Farm headquarters, but also  a prestigious educational system, historic stone wall buildings and white church steeples next to modern eco-industrial business parks.
