# List of round barns

What are termed round barns include historic barns having true circular designs and also octagonal or other polygonal designs that approximate a circle. In the United States, in a first era of round barn construction, from 1850 to 1900, numerous octagonal barns were built. In a second era, from 1889 to 1936, numerous true circular barns were built.
This list article includes surviving or historic round barns in Canada, the United States, and elsewhere. There were 19 historic round and polygonal barns in Canada identified as surviving in the 1970s, in a list compiled by members of a club and typed up by Katherine Kirkam. According to Matthew Farfan, nine round barns survive in the Eastern Townships of the province of Quebec, all close to the U.S. border.
Besides paying attention to Canadian barns, Kirkham also studied American barns; in the 1970s, she identified 444 surviving barns in the United States. Many of them are listed on the National Register of Historic Places.
Dale J. Travis has identified and photographed (or collected photos of) round barns and other round or polygonal buildings throughout the United States and Canada. His webpages document the loss of numerous historic round barns.
The periods during which round barns were built varies across U.S. states. Most of Indiana's round barns were built between 1900 and 1920, and their construction peaked in 1910. Iowa's peak years were from 1909 to 1922. All 44 of the historic round barns built in South Dakota were built between 1903 and 1946. North Dakota's peak years were from 1910 to 1916. South Dakota had none built before 1900 because the state had yet to be developed.

## Canada

As documented here, there are at least 11 surviving octagonal, true round, and other round-type barns in Quebec. A few others survive in British Columbia, Alberta and Ontario. A list of round or near-round structures in Quebec, including historic round barns, developed by Dale J. Travis has informed this compilation. Similar for other provinces at Travis site. Travis also includes less historic structures.
This includes others not in Travis's compilation, such as the Higginson Round Barn, which is an impressive and old one.

Gamel hexadecagon barn 16-sided Gamel barn in North Collins, New York
Schultz 15-sided barn (1918–1929) at Cohecton not listed due to DOE owner objection

McArthur-Martin barn in Kortright (1883) 16-sided
Parker 13-sided barn (1896) about 15 miles north of Kortright in Jefterson
"Roof types among the nominated examples include conical (for example the Schultz 15-sided barn at Cochecton, New York (1918), gambrel. (the Young round barn at Greene-1914), and domical (Bates barn at Greene)."
