Conservation-restoration of the Statue of Liberty Conservation-restoration of the Statue of Liberty A centennial conservation-restoration of the Statue of Liberty ("Liberty Enlightening the World") occurred between 1984 and 1986. The Statue of Liberty, by French sculptor Frédéric Auguste Bartholdi, is a colossal artwork on Liberty Island in New York Harbor, and is a part of the Statue of Liberty National Monument. Much of the restoration effort was based on unprecedented restorative methods, as metallurgical repair work on such a large scale had never been attempted. Many scientists, engineers, government organizations, and professional consultants evaluated and dealt with the various problems and tasks facing the restoration effort.
Statue of William the Conqueror is also a commemorative plaque. William carries a gonfalon (banner) donated by Pope Alexander II. The sculptor, in order to make the work appear realistic, based his design on the Bayeux tapestry. Created with the help of a national subscription, it was unveiled on October 26, 1851. The six other statues are a later addition of September 19, 1875. The French inscription on the plaque translates into English as follows: This monument was erected by national subscriptionThe equestrian statue on October 26, 1851The statues of six dukes of Normandy on September 19, 1875 The statue is located on Place Guillaume-le-Conquérant
