The village of Grignan grew up in the shadows of the dominant medieval castle, Château de Grignan. A fortress has been located on this site since the 11th century and it was transformed into a more palatial dwelling during the Renaissance. It became renowned in France when in the 17th century, the Marquise de Sevigne wrote in her letters about the brilliance of its court and the surroundings. A garden was created in her memory in 1996 - it sits below the castle off the road Cours Adhémar.
Other sights to see in Grignan include the collegiate church of Saint Sauveur, which dates from the 16th century, La Maison du Bailli (Bailiff's House), a 13th century court house and now a municipal building, and numerous fountains and the lavoir (wash house) in the market place. The market is held in Tuesday mornings.
The village is also proud of its rose gardens, with over 150 varieties on display throughout the village - best enjoyed from late April to June. There are some arts and crafts shops in the village where you can pick up souvenirs or something a bit more special. Local craftsmen include wrought ironmongers, jewellery makers, pottery; there are also a few art galleries, some of whom offer painting classes.
