The John Bloom Barn in Holland Township, New Jersey, is a complex structure comprised of a large Pennsylvania forebay bank barn with an attached two-story, three-bent ground barn that creates an “ell configuration” lining the barnyard on the northwest side. Dendrochronological analysis has shown that the ell portion of the building was constructed from reused timbers felled in the summer of 1836, the winter of 1840/1, and the summer of 1841.
