This old fortified town has oodles of charm, and there's plenty to look at - even without a visit to the two remaining wings of the château where dogs aren't allowed (entry charges apply). The building was used as a women's prison for a long time, although it's now been restored to its earlier grandeur.

Once the dog's had his comfort break, walk up to the town and through the fortified arch 'the Clock Gate' into the old town. The gate's a bit like something you'd expect to find at Hogwarts, with hidden trap doors and secret passages to confuse intruders. The square ahead of you has a number of restaurants/cafes with outside tables, and it's an atmospheric place to enjoy a meal and watch the world go by.
