Grignan is a village in the Provençal Drôme, in Tricastin region, a little step away from the Rhone Valley near Valréas and the enclave of Vaucluse. It is a pleasant area of hills, with Mediterranean climate, where are grown lavender and olive trees. Grignan is known by the Marquise de Sevigne a classic french writer of the 17th century, who stayed with her daughter, the Countess of Grignan, to whom the letters were intended. Grignan Castle dominates the village, many times revised, it has nothing to do with the medieval fortress built by Adhemar. Today is the most beautiful castle in the Renaissance style of Provence. It is held every summer in Grignan a Festival of litterature. More information and photos about Grignan on Horizon Provence.
