Speyer has the distinction of being one of the oldest cities in the entire country. Founded by the Romans, the town is blessed with incredible architecture, especially the Speyer Cathedral, a Romanesque behemoth which dominates the skyline. The red-hued attraction aside, the Gedächtniskirche and Dreifaltigkeitskirche are other significant churches in town. While the historic relics are aplenty, a visit to the Technikmuseum Speyer will bring you face to face with the history of modern transportation. Definitely a premier tourist city, Speyer is well worth your time.
