Centennial Village Museum immerses visitors in an outdoor working reenactment of the settlement history of Greeley and Weld County from 1860 to around 1920, granting access to more than 30 different historical structures across 8 acres, including the courthouse, Weld County's oldest existing structure. The Cowboys and Cattle Drives living history program lets visitors observe "real" cowboys of the time, and the streetcar stands as a beguiling relic of bygone transportation forms. The younger members of your party can entertain themselves on the merry-go-round that revolves outside the one-room schoolhouse, at the penny-pinch machine, or by interacting with the menagerie of miniature farm animals and hungry spectators that graze in the agricultural area.

Village explorers can redeem the included merchandise voucher at Selma's Store, which serves as the entrance to Centennial Village. Visitors can purchase souvenirs from the selection of books, tea sets, children's toys, pokers made in the blacksmith shop, or, for those with an idle cache of misshapen wrought iron in their home, an actual blacksmith.
