Arcadia Round Barn, Agricultural barn on Route 66 in Arcadia, Oklahoma

The Arcadia Round Barn is a circular barn on U.S. Route 66 in Arcadia, Oklahoma, built in 1898 by farmer William Harrison Odor. Its walls and roof rafters are made of native bur oak boards soaked while green and forced into curves. The roof spans 60 feet in diameter, and a second level was built inside for community gatherings.

William Harrison Odor built this circular barn in 1898 when the area was focused on farming. It later became a notable landmark along Route 66 after that highway was established in the early 20th century.

The second floor functions as a community space, hosting music performances, weddings, and local gatherings that bring residents together throughout the year.

The building sits directly along a historic highway and is easy to spot and reach from the road. Visitors should keep in mind it is a working structure, so approaching with respect and caution when exploring is important.

The barn's 60-foot-diameter roof collapsed in 1988 and was rebuilt by volunteers led by Luther Robison, with restoration finished in 1992. Its curved wall and rafter boards are native bur oak, soaked while still green and bent into shape rather than cut in arcs.
