I don't know that this park is actually called Léon Bonnat, but given that I can't really find a name for it and that it is in fact on Avenue Léon Bonnat, it seemed like this was the best name to give it. It is in a newer part of Grand Bayonne, not far from the Tourist Office and the main Post Office, so I doubt that the park itself is of any historic significance. However, it is a pretty and well-maintained green space near the Adour where you can relax in relative peace and quiet before heading off to do more sightseeing or shopping. There are no spectacular flower dispays or rare flora - this is just a municipal park intended to provide a bit of relaxation. I had lunch here - there are a number of bakeries and sandwich shops nearby - and it seems to be the perfect location for a small picnic on a warm summer's day.
ProformArt is a small private art gallery behind Bayonne Cathedral. An exhibition had opened the day before I visited and the gallery was offering free food and drink. Considering they open a fresh exhibition of work every six weeks or so, your chances are reasonable to get free food ;-)
The gallery is located on the ground floor of a typical, pretty Bayonne town house. The exhibition when I visited comprised of a wide mixture of drawings, paintings, photography and sculpture. They were almost exclusively of women with no clothes on ;-o
