For most people, the term “root cellar” evokes an image of a brick or stone masonry subterranean structure tunneled into a hillside. These classic root cellars are only one of a number of different types of structures used to preserve root crops, vegetables and fruits over the past 400 years. The other structures include subfloor pits, cooling pits, house cellars, barn cellars, field root pits & trenches, and root houses. Root Cellars in America provides a history of all the structures, discusses their design principles, and details how they were constructed. The text is accompanied by period illustrations from the agricultural literature along with archaeological photographs. There has been a long standing debate whether the stone slab roof and corbelled beehive shaped subterranean structures in northeastern United States are root cellars or Native American ceremonial stone chambers. New research indicates some are root cellars and some are ceremonial chambers. The third edition has a new chapter exploring this topic. Detailed guidance is provided on how to distinguish the two from each other based on differences in their architectural traits.
