Round Barn

William Harrison Odor was an Arcadia-area farmer who arrived in what was then Indian Territory in the early 1890s and established a working farm on the land surrounding what is now Shire Avenue. Odor was a competent amateur builder and constructed several of his own farm structures, including the eventual Round Barn. Construction of the barn began in 1898 with Odor harvesting native bur oak from his own property and milling the timber on-site for the barn's structural members.

The round shape was deliberate and driven by Odor's interest in then-current agricultural theory. Late 19th-century farming literature had begun promoting round and polygonal barn designs as superior to traditional rectangular barns on multiple counts — better wind resistance, more efficient interior layout, easier herding of livestock around a central feed area, and more uniform light distribution through high windows. The tornado-resistance argument was particularly persuasive in Oklahoma where tornadoes were a regular threat, and Odor decided to test the theory with his own construction.

The barn measures 60 feet in diameter and 43 feet to the peak — substantial for a single-family farm of the era. The interior is organized across three levels: a ground floor for livestock and equipment, a middle hayloft level, and an upper loft that originally stored seed and tools. The bur-oak timber framing is exposed throughout the interior and is the most architecturally striking feature for visitors today — the curved roof framing in particular is genuinely impressive and is the most-photographed interior element. The acoustic properties of the curved interior are also remarkable; sound carries oddly inside the barn in ways that surprise first-time visitors.

By the late 1980s the Round Barn had deteriorated to the point where collapse seemed possible within a decade. Luther Robison, a retired engineer living in Arcadia, took on the restoration as a personal project and began organizing volunteer work crews in 1988. Robison's engineering background gave the restoration substantial technical credibility — the structural assessment, the foundation stabilization plan, and the roof reconstruction sequence were all engineered properly rather than improvised.

More than 200 volunteers contributed weekend labor over roughly four years. The work included clearing decades of accumulated debris from the interior, stabilizing the shifted foundation with new concrete piers, removing and replacing failing sections of bur-oak siding using period-appropriate construction techniques, rebuilding the roof with new framing that matched the original curved profile, and converting the interior spaces for museum and gift shop use. The restoration received a Governor's Outstanding Achievement Award for historic preservation in the early 1990s.

Robison continued as an active board member and informal steward of the barn until his death in the 2000s. The restoration he led is widely cited as one of the more successful all-volunteer historic preservation projects in Oklahoma and is credited with saving a genuinely irreplaceable example of late-19th-century agricultural architecture. The barn was listed on the National Register of Historic Places in 1977 and remains protected as a Route 66 cultural landmark.

The ground floor is the museum exhibit area. Display cases and interpretive panels cover William Harrison Odor's biography and farming operation, the late-19th-century round-barn construction movement (with photographs of other surviving and lost round barns across the Midwest), the late-1980s restoration process led by Luther Robison and the 200-plus volunteers, and the broader agricultural history of pre-statehood Indian Territory and early Oklahoma. The exhibits are modest but well-organized; expect to spend 15 to 25 minutes reading through them.

The upper floor functions as a gift shop and rotating local art gallery. The gift shop sells Route 66 merchandise (postcards, magnets, t-shirts, books), Arcadia-specific items including small reproductions of the barn, and locally-produced crafts from Arcadia-area artisans. The art gallery rotates exhibits of Oklahoma photographers, painters, and craftspeople — exhibits typically change every two to three months and many of the displayed works are for sale. The proceeds support ongoing barn maintenance.

The interior acoustic effect is one of the barn's quieter highlights. The curved walls and ceiling produce unusual reverberations — clapping in the center of the ground floor generates a layered echo that takes several seconds to die out, and conversations from across the room can sometimes be heard surprisingly clearly. Local musicians have occasionally performed acoustic sets inside the barn specifically to use the natural acoustics; check ahead if you're interested in catching a performance during your visit.

The Round Barn is officially open Tuesday through Saturday from 10am to 5pm, with the museum and gift shop both operating during those hours. Sunday and Monday closures are firm; plan your visit accordingly. The barn is staffed by volunteers and donations from the Arcadia Historical and Preservation Society, and a small donation box at the entrance is the property's primary funding source. Suggested donations are $3 to $5 per adult, though admission is genuinely free for those who can't or don't want to contribute.

Most visitors spend 30 to 45 minutes at the barn — enough time to read through the ground-floor exhibits, browse the upper-floor gift shop, take photographs of the exterior and interior, and have a brief conversation with the volunteer docents who are usually happy to share construction details or restoration stories. The exterior is photographable from multiple angles; the south-facing side typically has the best afternoon light, while the east-facing side is best for morning visits.

Combining the Round Barn with POPS 66 Soda Ranch is the standard Arcadia plan and the two are essentially co-promoted as the town's pair of must-stop Route 66 attractions. The natural sequence is the Round Barn first (it's smaller, quicker, and closes at 5pm) followed by POPS for a meal and the soda wall (open until 9pm with the LED bottle lighting up at dusk). Total time for both stops runs 90 minutes to 2 hours. Arcadia sits about 25 miles northeast of Oklahoma City, 20 miles west of Chandler, and 10 miles north of the Edmond suburb — making it an easy day-trip from any of those bases.
