Bordering Provence is Nimes, known for its Roman ruins, in particular the amphitheatre is worth a day trip to this town. There's a lovely pedestrian-only shopping area, with a crepe stand that my husband and I still talk about.
There's also a labyrinth of winding little streets full of trendy shops, and every year there's a Marche de Noel ("Christmas Market") near the Maison Carree, and in the summer you can find the Jeudis de Nimes ("Thursdays of Nimes"), where you can find food, dance, street merchants selling almost anything you can imagine, and plenty more, late into the night.
