Someone asked about St Emilion. For an incredible adventure there is a store near to the tourism office that has , IIIRC, every producer of St. Emilion represented, there are a lot of labels! the city istself is built into a bowl so there are some interesting angle looking out from the city.
The Cathedral was built underground and is now used twice a year for the wine growers (what is the word?) convention a big event with much pomp and ceremony
