I am french and visited the Guedelon castle a few years ago.

Before visiting the castle, I had done a full year trip around the world to see all the greatest human made monuments (Angkor wat in Cambodia was my favourite).

I was stomached when I realized the Guedelon castle surpasses all that I had seen so far.

Highly recommended for anybody visiting France.

From the website (http://www.guedelon.fr/) it looks half-finished and not too visually impressive, although interesting nonetheless. Could you explain what makes it surpass all other human monuments?

Indeed, I can see what looks like a rather more interesting castle (built on the glacier eroded plug of an ancient volcano) by turning round and looking out the window:

Now how historians from the XXXth century will make sense of that, I'd like to know :)

Dude, there's cities with trains running above, below and on the ground. Not much of what we do will make sense in 20 centuries down the line.

The bigger question is, did anyone do something like this in the past and seriously fuck with the archaeological time line?

Assuming time machines are possible to build, then it is a good assumption that at some future point in time, whether it's hundreds or even thousands of years from now, a time machine will be built. Then, somebody will get into that time machine, travel back into the past, and mess it up. Thus, someone from the future has probably already messed up the past.

In fact, this new castle in Arkansas may be a symptom of the damage already done to the space-time continuum. Frickin time vandals!

Through Internet archeology. Hello, readers from the 28th century!

Deal! I propose a Long Bet: http://www.longbets.org/

There is an older (and I think better known, and possibly more interesting) case, that of the Facteur Cheval: - http://www.facteurcheval.com/ - http://en.wikipedia.org/wiki/Ferdinand_Cheval

He built a palace all on its own, with his own distinct style, back in the early XXth century.

That's about an hour from my parent's house. All kinds of bizarre stuff built out there. Cheap land and labor and few to no building codes.

It was a mistake not to oppose the Frenchman's arrival in our lands. After the Frenchman finishes the castle, he will start breeding orcs.

What a beautiful project!
