St. Mary's City in St. Mary's County, Maryland — The American Northeast (Mid-Atlantic)
How Old Is This Barn?
The central section of this structure is the oldest part dating from 1785. Originally, it had sheds on each side that protected the core building. These sheds were replaced several times and served a range of functions over the course of the barn's history. The current sheds are similar to the originals but were built in 2008.
Living trees lay down annual rings showing each year's growth. Variations
In the 1980s, scientists conducted the first major tree-ring dating study in the Chesapeake region. Focusing upon Southern Maryland, they sampled 64 trees and 24 buildings, and created a sequence spanning 410 years from 1570 to 1980. The wooden timbers in this barn tell us it was constructed in A.D. 1785, and the wide floorboards were added in A.D. 1848. Results of this tree-ring study surprised everyone. Many structures believed to be of 17th-century date were actually built in the 18th century. These findings changed our understanding of the architectural history of this region.
