They were built on a rectangular plan, with a large central square and straight thoroughfares running at right angles or parallel to one another, this uniformity of construction being well exemplified in the existing bastide of Monpazier (Dordogne) founded by the English in 1284.
The name Castelsarrasin appears in the 13th century, when the village of Villelongue was replaced by the present bastide.
The La Bastide Saint Dominique Grenache Secrets de Pignan is an especially unique version because it is made only from Grenache with no other varietals blended in.
However, the Bonnet family's La Bastide Saint Dominique uses 100 percent Grenache in its 2003 Secrets de Pignan.
