Ozark Medieval Fortress was a project designed to construct an accurate replica of a 13th-century French castle in Lead Hill, Arkansas. Construction was carried out on the site using only materials and techniques appropriate to the 13th century. The ground was broken in 2009, with the expectation that completion would have taken about 20 years.
The project was inspired by Guédelon Castle in France, which is the first attempt to build a medieval castle using accurate construction methods, started by Michel Guyot. Two French citizens living in Arkansas offered to sell Guyot part of their land for the building of a similar fortification. Guyot accepted, and construction began in June 2009.
