"The Roquebrune-Cap-Martin Castle, which is also called Grimaldi Castle after its former Monegasque owners, was built in Roquebrune-Cap-Martin by Conrad I, Count of Ventimiglia, at the end of the 10th century of the Saracens, who had raged here for almost two centuries. The hilltop castle is located at the highest point of the municipality, which has retained its medieval character to this day. Since February 28, 1927, the complex has been a listed monument.
