Aachen Cathedral was built during the reign of Charlemagne and completed in 786AD, when it was the largest dome structure north of the Alps. The remains of Charlemagne were interred here, and the tomb can be seen to this day. There is a different mixture in building styles to the cathedral, after extensions have been added several times throughout the ages.
The city hall was constructed in the 14th century, and lies between the Markt (market place) and the Katschof (the square that lies between the cathedral and city hall). Highlights inside include the first-floor coronation hall and five frescoes by noted Aachen artist Alfre Rethel. These frescoes depict scenes from the life of Charlemagne.
Located in Friedrich-Wilhelmplatz, the Elisenbrunnen (Elisa Fountain) is a symbol of Aachen's historical role as a spa. It was constructed in 1827 where it served as a drinking and promenading hall. Visitors today can sample the healing thermal waters of Aachen from the fountain. Famous visitors to Aachen over the centuries, are named on marble plaques surrounding the monument.
The remains of the medieval city walls of Aachen still remain standing in some places around the city. Many have been incorporated into more recent constructions, whilst others are visible and even include five towers which still stand today. Two city gates remain, the Pottnor, which is located half a mile northwest of the cathedral and the Kleinmarschiertor, which is found near the railway station.
Aachen's Cathedral Treasury is considered to by the most important ecclesiastical treasury north of the Alps. Housed within, are arts pieces from the late late Antique, Carolingian, Ottonian and Staufian epoch. These include treasures such as the "Cross of Lothair" and the "Bust of Charlemagne". Combined with other exhibits, these works demonstrate Aachen Cathedral's importance as a medieval treasury. Guide-books are available for visitors to explore the treasury on their own.
