The Ark Staircase
A neo-Gothic sandstone portal leads into the Ark Staircase, which was built in 1840. The ascent offers splendid views of the Aachen Cathedral and also the opportunity to learn all about the International Charlemagne Prize and its laureates. In front of the Coronation Hall, two colossal murals by Albert Baur from the years 1900/01 cannot fail to catch the eye: to your left, the citizens of Aachen swear an oath to the Emperor Friedrich Barbarossa to build a city wall; to your right, the legend of Nero Caesar’s brother Granus Serenus discovering Aachen’s thermal springs. Above the entrance itself you can see Charlemagne’s monogram.
