On the occasion of the 400th birthday of  <a href="https://en.wikipedia.org/wiki/Adam_Ries" class="extiw" title="en:Adam Ries">Adam Ries</a>, the Annaberg Historical Society decided in 1891 to put up a monument to the mathematician. The sculpture by the Dresden sculptor, <a href="https://de.wikipedia.org/wiki/Robert_Henze" class="extiw" title="de:Robert Henze">Eduard Robert Henze</a>, was not dedicated until 5 November 1893 because of financial difficulties. In 1943, the bronze bust was melted to make armaments and it was replaced ten years later by a sandstone copy. It now stands before the Adam Ries Haus.
