Bassoues
Bassoues is worth a stop, not only because of the 14th century donjon, but the town itself is a super little "bastide," where people live today. Bastides, fortified villages from the Middle Ages, have a central square with covered market in the middle, and stone walls and towers for protection.
Walk through the town to get a feel for the Middle Ages - the covered market in the middle is still in use, on Saturdays and Sunday's there's a farmer's market.
Climb up the donjon of Bassoues, a 141 foot tower, with walls 6 feet thick. Inside the tower, check out the each floor reconstructed as living spaces, with big fireplaces and window seats, sinks and garderobes (latrines). On top of the castle keep are guard towers in the four corners and a bird's eye view of the town below.
