These are described in more detail in the individual annotations.
- Where? Stone walls around former agricultural fields occur throughout the world. They are especially common in the British Isles and in New England.
- How many? There are too many to count. Certainly, there are tens of thousands of segments of stone walls.
- How long? If you added up all of the length of stone walls in New England and eastern New York, it would probably reach almost to the moon. One estimate is 240,000 miles.
- How high? Most walls reach higher than the knee of an adult but lower then the hip. This makes them about 2 feet high. Very few are chest-high or taller.
- How built? Most walls were made by simply setting stones on top of each other like cordwood or bricks. Carefully built ones, in which stone was quarried, hammered to fit, and carefully selected were built by craftsman.
- When? New England stone walls were built in the early 1600’s and continue to be built today. In inland regions of New England, however, most were built between the time of the American Revolution and the Civil War. A large portion of the walls was built in the fifty-year period between 1780 and 1830.
- Who? The farmers who cleared the fields built most stone walls, especially those that are not carefully laid. Many well-built walls were built as construction projects when low-cost labor was available, whether from wage earners, slaves, prisoners, or family members.
- Why? Most stone walls, especially poorly constructed ones, were built to help hold the stone that had accumulated in fields. Often the stone was incorporated into a fence. Some stone walls were built specifically as fences, but this is rare. Even fewer were built for architecture’s sake.
