The Grimaud Castle appears in the texts for the first time in 1119. At that time, it belonged to the Viscounts of Marseille. During the next five centuries, it will go from hand to hand, before being dismantled on Mazarin's orders in 1665. In the late 17th century, the land belonged to the family of Castellane-St-Juers who restored the castle and made it more comfortable. Unfortunately, in 1791, the castle was dismantled again by the revolutionaries.

In 1928, the ruins of the castle were listed historical monuments in order to protect them. At that time, restoration work began to strengthen the castle. After this work, the castle was listed historical monuments as well.

Today, the owner, the Earl of Senard, wants to promote the cultural aspect of the castle and has made ​​it available to the municipality. To go a little further, he built a performance area where concerts are held, particularly the Grimaldines (a festival of world music) during the summer.
