Napoleon Bonaparte
Erfurt's early 19th-century history is heavily influenced by the presence of Napoleon. His legacy is clearly visible at Petersberg Citadel, and in the grandeur of the Thuringian State Chancellery where he was resident and where he welcomed the poet Johann Wolfgang von Goethe. Napoleon also left his mark on the Imperial Hall, venue for the diplomacy and ceremonies of the European Congress of Erfurt in October 1808.
