In the Perigord region of South West France you find the black Perigord and there the town Sarlat.
The area is named after the deep black slate used there for roofing.
Make sure your roof beams are sturdy though, it weighs between 500kg and and tonne per square meter.
A few photos of the town.
Michel de Montaigne, the first western essay writer lived in the purple Perigord, further west. A wine producing area.
Here is his friend Etienne de la Boétie’s house.
How’s that for a solid lintel.
Good for a thousand years or more.
And a final view before we leave town
