Far less known than the Monumental City's other memorials, but no lesser in size, is the Battle Monument in the median across from the Baltimore Circuit Courts. Dedicated to the Battle of Baltimore in the War of 1812, it stands on an Egyptian tomb-like base, with Baltimore's fallen soldiers' names engraved. Lady Baltimore stands atop the column, bearing a wreath of victory. It is the oldest structure in this part of the city.
