Velleron is a municipality organised around its château which stands at the highest point of the village. Velleron was originally a Gallo-Roman oppidum, and became a fortified village in the Middle Ages. In the 17th century, and up until the revolution, the village was the joint property of the Crillon and Cambis families. Today the former château of the Crillon family houses the mairie.

As you walk from Place du Château to Place de l'Eglise you will come across the stone fountain of Caromb, the recently restored church of Saint Michel (in olden days the priory of Notre Dame de Nazareth), and you will also discover the beautiful façades of houses once owned by notables. A few steps away, on Boulevard du Barri, cut out from the ramparts, the remains of the 17th century olive oil mill are bound to surprise you. It's also worth taking a look at the old hospital dating from the 18th century, and admiring its fountain.
