On Saturday, June 26 2010, a reconstitution of the naval conflicts of the era will be held under the castle walls, during the traditional ' Fete de la Tarasque'complete with boats, guns fireworks, 200 locals in costumes. This will largely beat the retransmission of Fifa World cup matches, in my opinion. Even if you miss the party, this place is a must-see of every voyage in Provence, with a lovely reconstitution of medicinal and aromatic garden in one of the courtyards. Tarascon Itself, half an hour from Avignon, is a maze of cobbled streets leading to old chapels, museums, the Soleiado manufacture of fabrics, and good priced restaurants ( I recommend the Brasserie du Palais, were Bernard and Charles speak english, for breakfasts and lunch.).
Tarascon is an interesting site, where the Rhone river flows at its mightiest, just before entering his delta know as the Camargue. It is a major crossroad for rail, linking Italy, Spain and northern Europe, and was heavily bombed before the allied forces landing operations in Provence in 1944 : last year's fete de la tarasque was devoted to a reconstitution of the Allied landing near Saint Tropez.
