Chârost is a very old village located about 15 miles west of Bourges in the Berry. It's more than an hour's drive from Saint-Aignan. CHM and I went there on our way back from Bourges in mid-June.
The guide books say there is a château, or at least the ruins of one, in Chârost, but it is almost completely hidden behind walls and trees. We got just a glimpse of it. We stopped and looked around the church grounds. We even went inside the church — which meant going to get the key at the Mairie, the village hall, next door — but about half of it was closed off because it's being restored.
The town itself didn't look very prosperous, and it was nearly deserted at 5:00 p.m. on a weekday. It's not far from Bourges, but much closer to Issoudun. The Reuilly and Quincy (AOC Sauvignon Blanc) wine areas are to the north.
This part of the old Berry province used to be a mining center. There's a lot of iron ore in the local rock. The church in Chârost is built of limestone that contains a good amount of that ore, and the church walls look as if they are rusting. I guess they are.
The Eglise St-Michel is an abbey church in Romanesque style dating back to the 12th century. I want to go back one day to see the part of the church that was closed off to visitors.
