I heard a little bit about an intriguing story on an NPR show this afternoon about the Ozark Medieval Fortress. An authentic Medieval castle is being built in northern Arkansas (of all places -- one builds where one is offered land). The builders are using local materials and will do all the work according to the current understanding of how builders in the 13th century worked. Building began last year. The site opens this month as a living history museum. Visitors will be able to talk to the workers as they work. They may not be hiring, but they appreciate the help of volunteers. They expect to complete the whole thing in 2030 -- yep, it will take them 20 years.
My friend and debate partner will appreciate the discussion of the rope with 13 knots, which is described under the Construction menu.
