Historic Forestville presents life in 1899 Forestville, Minnesota. Once a bustling trade center, in 1868 the Southern Minnesota Railroad built tracks elsewhere, bypassing the town and significantly impacting its economy. 31 years later, the town's 50 residents all worked for Thomas Meighen (1855-1936); and were paid in housing and store credit. The historic town is interpreted via living history docents, who depict the Meighens and their employees. Five historic structures remain on site: the store, Meighen home, barn, carriage barn, and granary. All crops on site are heirloom varieties and are open pollinated.

The site offers one-hour tours guided by living history figures, costumed interpreters, demonstrations, heirloom crops, and summer camps. The website offers historic photographs and a suggested reading list.
