It is a tessellation designed by Christiane Bettens, while the diagrams are in the book “Origami Tessellations" authored by Eric Gjerde.
In the book, it says that the tessellation is named after an architectural tilling (which inspired the tessellation) born in Chateau-Chinon, France.
It is the first tessellation in the book labelled as “intermediate”.
Why intermediate? Well, besides the almost-confusing way to fold the
various shapes in the model, you have to do an awful lot of creasings.
If you make a simple mistake in making the creasings, your whole
artwork will be like the rags used to wipe the asses of horses pulling
the carts in old Spanish places.
But, if you do everything right, you will be rewarded with a nice tessellation consisted of irregular octagons and squares.
Once again in the rating of “if it is easy or hard” well I’ll give it a 7.
The posterior is also beautiful (though I do not have a picture).
It’s one of those tessellations where you cannot decide which side are
you going to display. But, meh, if the book says this is the front, then
so be it.
