The river Mulde flows through the town, a significant section of which is situated in a floodplain. Massive floods in 2002 washed away the old Pöppelmannbrücke bridge and caused significant damage to buildings in the town. In the summer of 2013 there was further flood damage.
Grimma has been the site of many historic structures, including a town hall dating from 1442, a famous school (the Fürstenschule) erected on the site of a former Augustinian monastery in 1550, and a school of brewing.
^The latter has been claimed in Encyclopedia Britannica 1911: Grimma as follows: "There are also a modern school, a teachers' seminary, a commercial school and a school of brewing." Following three sources are given, the second badly misspelled: "See Lorenz, Die Stadt Grimma, historisch beschrieben (Leipzig, 1871); Riissler, Geschichte der kiiniglich sdchsischen Fi rstenand Landesschule Grimma (Leipzig, 1891); L. Schmidt, Urkundenbuch der Stadt Grimma (Leipzig, 1895); and Fraustadt, Grimmenser Stammbuch (Grimma, 1900)." (all three German language)
