Sarlat-la-Canéda
history
The capital of the Périgord Noir and one of the most complete medieval centres in France, with a density of listed buildings almost unmatched in the country. It survived because the town was economically stagnant for centuries and nobody had the money to knock anything down; in 1964 it became France's first protected sector under the Malraux law.
Tip
If you can, come on a Saturday morning: the market fills the square and the streets of the whole old town and is an institution in the region. And come back at night, when the streets are lit by gas lamps.
