Plagny is a community just south of the city of Nevers and is about a two-hour drive from Saint-Aignan.
Tuilerie is the word for tile manufactory. The Tuileries Gardens (and former palace) in Paris are built on the site of an old tile works. Tuiles mécaniques are a special kind of interlocking roof tiles. The tiles on our very own roof are mécaniques, but they don't look at all like this; they're big and rectangular and very dark brown, and probably about the same age as the house (50 years). I learned what they are called and how they work when we needed to have some roofing repairs done a number of years ago. There's nothing mechanical about the tiles; that word refers to the nineteenth century automation of the process for making them.
