A medieval castle is being built in France. There’s also a Youtube channel.

2016-09-15: If you’re ever in this part of France, I highly recommend a visit to the slowest castle construction site in the history of the world.
Guédelon Castle is a project started in 1997 by Michel Guyot and Maryline Martin in the Burgundy region of France. The castle is styled on typical French medieval chateau-fort, modeled on designs from the 13th century, and is being built using techniques and materials available to masons and builders 800 years ago. The Guédelon project has now become a tourist destination, and employs dozens of workers. The castle is due to be completed in 2023.
