Built into the side of a cliff in 1927 at the base of Colline du Château or Castle Hill is a 105 foot war memorial called Monument aux Morts. It consists of an urn within a niche and two high reliefs: the left represents war and the right is for peace. It honors over 3,600 men from Nice who died during World War I. It is also a somber remembrance of the 1.5 million French people who lost their lives between 1914 and 1918.
