Jacques IV of Matignon (1689-1751) was a descendant of the Estouteville family, lords of Valmont who built the château in 1110. He married Louise-Hippolyte Grimaldi in 1715 and acceded to the throne in 1731, taking the regnal name Jacques I of Monaco and bringing the Valmont lands to the House of Grimaldi. The château remained in the hands of the Grimaldis until 1805. H.S.H. Prince Albert II will return to the lands of His ancestors in September.
