In 1997 a team of roughly 70 historians, archaeologists, and craftsmen set out to build a 13th century style castle in a forest two hours outside of Paris using only period appropriate tools. Every stone, tile, and brick is handmade, every tree is hand-felled, and even the trebuchet-looking construction set-up was hand-crafted.
The BBC described the Guédelon Castle as "the world's biggest archaeological experiment" and it's currently set to be completed in 2022 as a tourist and educational landmark.
