The best thing to do on a rainy day is to go out for a walk. Take your umbrella, stop by a book store, and go to the nearby garden. Here in Nîmes the biggest garden/park is Jardins de la Fontaine, or the Fountain gardens. Signs of spring are everywhere… like here, where the weeping willow is blooming.
The pool is actually a real spring, and the very spot where the city got its start: a celtic tribe had built a village around the sacred spring dedicated to the goddess of Nemausa, and the Romans continued the work by building a bath complex with a library and a theater, and expanding the city of Nemausus further.
In the 18th century a civic park à la française was built in the same place, and nowadays it’s a place for all the citoyans to spend time and relax. Even on a rainy day!
