A Luther Monument (German: Lutherdenkmal) is a monument dedicated to the reformer Martin Luther. The oldest one from 1821 is in Wittenberg. The largest one, the Luther Monument in Worms, was unveiled in 1868 as a composition of several statues, designed by Ernst Rietschel. Several monuments in the United States use a copy of Rietschel's main statue, including the Luther Monument in Washington, D.C., from 1884.
