From Fort St-André with its two mighty round towers, built in the second half of the 14th C by John the Good and Charles V, there is a magnificent view of Villeneuve, Avignon, Mont Ventoux and the Lubéron and Alpilles mountain ranges. The massive walls enclose the little town of St-Andre, a Benedictine monastery and the Romanesque Church of Notre- Dame-de-Belvezet.
