The Holy Roman Empire capital

The Holy Roman Empire never had a single permanent/fixed capital city. Usually, the Holy Roman Emperor ruled from a place of his own choice. This was called an imperial seat. Seats of the Holy Roman Emperor included: Aachen (from 794), Palermo (1220–1254), Munich (1328–1347 and 1744–1745), Prague (1355–1437 and 1576–1611), Brussels (1516–1556), Vienna (1438–1576, 1611–1740 and 1745–1806) and Frankfurt am Main (1742–1744) among other cities.
