Guédelon castle

 In the Puisaye region of French Burgundy, they are building a thirteenth-century castle. Its name is Guédelon.

 The project began in 1995 as an attempt to build a castle using medieval techniques.  Nearly thirty years later, they hope they are close to finishing, and they have learned a tremendous amount in the process about how castles were built in the thirteenth century.  The builders call this "experimental archaeology."

The process began with studying real castles.  Although all medieval castles have been modified over the centuries (and many are now in ruins), close analysis can show how (one simple example) walls were built with careful stonework for the inner and outer sides, and an inside filled with rubble.  A lot of medieval buildings still have builders' marks on stones or beams, giving additional clues to their construction.

Added to this are medieval manuscripts which portray castles and other buildings under construction.  There are even a few handbooks from the late Middle Ages giving cryptic instructions.  The modern French builders' guilds, the ones who repair old buildings, have retained a lot of useful information over the centuries.

But in essence the builders at Guédelon are reverse engineering a castle, trying something and seeing if it works to produce something that looks real.  Any thought someone might have had in 1995 when they started, that the simple folk of the thirteenth century would not have had the sophistication of modern builders, was quickly dispelled.  Medieval builders didn't have our machines, but they knew exactly what they were doing and what would work.

Timbers (mostly oak) are cut with medieval style axes and saws, and stones are chiseled and shaped with medieval style chisels.  The sandstone from which most of the castle is being built is locally quarried, and the limestone, used for fancy vaulting and decorative carvings, comes from just a short distance away.  Most of the oakwood is from nearby.  This reflects what real thirteenth-century builders would have had to do, get as much local as they could because of the enormous transportation costs of heavy materials in a pre-truck world.

Over the last quarter century, a lot of people interested in historical reconstruction have come to learn and work at Guédelon. The builders reconstructing Notre Dame in Paris, after the fire, are trying to restore the timbers and roof to something like the thirteenth-century original, and many of the workers had been trained in medieval techniques at Guédelon.

Guédelon welcomes visitors.  You can visit during the summer months, for only 14 euros each (less for children).  They are eager for people to see their work and to teach them about medieval techniques.  I would guess that once the castle is finished they will be able to rent it out as a movie set, because it will (of course) look like a thirteenth-century castle looked in the thirteenth century.  European movies set in the Middle Ages often use real castles as a backdrop, but they have to shoot carefully (or use CG special effects) to avoid the ruined bits (Hollywood movies tend to go in for the unconvincing stage set).

The project has an extensive website (in French and English) giving the story of how they decided to build a medieval castle in the twenty-first century and illustrating construction methods, available here.
