In 1995, the Cathedral Treasury was completely refurnished in accordance with the newest conservation and pedagogical knowledge. An area of over 600 m2 contains over a hundred artworks, divided into five thematic groups. One conceptional area is the documentation of the Cathedral as the church of Charlemagne. The late gothic silver-gilt Bust of Charlemagne, a model for countless later reliquaries stands in the centre of this section. The Persephone sarcophagus, the Roman marble sarcophagus of the early third century in which Charlemagne was buried in the Cathedral is also here. Among the objects in the Cathedral Treasury which were connected with Charlemagne is an Olifant from eleventh centurySouthern Italy or the east, which was long considered the Hunting Horn of Charlemagne. There is also the so-called Hunting Knife of Charlemagne, dating to the eighth century. It and the Petrusmesser in the Bamberg Cathedral Treasury are the only known Medieval knives that were kept above ground and therefore had a special significance from the beginning. All other similar pieces have been found in archaeological contexts. The hunting knife, made of Damascus steel is classified as Anglo-Saxon or Scandinavian. The associated sheath probably dates to the eleventh century and bears an Old English inscription, reading BRHTZIGE MEC FECID. The second section contains objects connected to the liturgy, including the Cross of Lothair, the Aachen Altar, the Carolingian Treasury Gospels, a masterpiece of medieval illumination. In addition there is also the late gothic pieces of goldsmithHans von Reutlingen. Artworks which were used at Aachen at the Coronations of the Holy Roman Emperor between 936 and 1531 form a third thematic category, including the masterfully produced ivorysitula, a vessel for Holy water made in Trier around the year 1000 and decorated with rich reliefs, as well as the Ottonian Liuthar Gospels which are exemplary of their period. The relics of the Cathedral and the pilgrimage to Aachen and the cathedral as a church of Mary are the fourth and fifth categories. The reliquaries and the so-called Hungarian Donations, as well as pictures and sculptures of the Theotokos are displayed here. Gems which donors and patrons gave to the Cathedral treasury are displayed in vitrines. Items from the rich textile collection of the treasury are in constant rotation in the basement, with the coronation cloak, the Cappa Leonis, falsely named after Pope Leo III in the centre.
History
Treasury
"Since I have seen every royal marvel, no-one living has seen a more marvellous thing," wrote Albrecht Dürer in his travel diary, when he visited Aachen in 1520 on the occasion of the Coronation of Emperor Charles V. By some miracle, the unique collection, the most important north of the Alps, has survived intact in the Cathedral and its Treasury to this day. Its outstanding position is due to the fact that Aachen Cathedral hosted the coronations of thirty Kings of the Romans between 936 and 1531. Only after being anointed at Aachen could the ruler be crowned Holy Roman Emperor in Rome. Countless precious objects entered the collection as royal donations, others were essential parts of the coronation ceremonies. As they grew over the centuries, the contents had a tumultuous history. They were sent away during the Thirty Years' War and again in 1794 when the French Revolutionary troops occupied Aachen and incorporated it into the département of the Roer. In August of that year the treasure was taken to the Collegium Liborianum, the Capuchin monastery in Paderborn, where the three items of Imperial Regalia hitherto in the possession of the Cathedral college. The rest of the collection was sent back to Aachen Cathedral where they were carefully walled up in the south tower of the Westwerk. At the urging of the Reichskonservator Robert Hiecke and Provinzialkonservator Franz Wolff-Metternich who was in close contact with Cathedral chapter and the civic administration, the pieces stored at Albrectsburg were taken to Siegen on 13 September 1944 and were stored there, in Hain Tunnel, along with the Essen Cathedral Treasury, the Trier Cathedral Treasury, the most valuable items of the Rheinish Museums and the wooden doors of St. Maria im Kapitol. On Easter Monday 1945, the young vicarErich Stephany, accompanied by the American art protection officerWalker Hancock, set out for Siegen, to inspect the six boxes of stored Treasure. On 7 May he left for Siegen again, to bring the Treasure back to Aachen. However, the delivery was delayed by the Capitulation of the Wehrmacht signed the same day. The collection was only returned on 26 May thanks to Hancock, who prevented their transfer to Marburg, loaded the Treasure, copies of the Imperial Regalia, and the wooden doors of St Maria in a lorry without authorisation and transported them to Aachen and Cologne.
Treasury Chamber
Until 1979, the Treasure was housed in a 90 m2 room from Carolingian times on the east side of the cloisters. In 1975, on account of the significance of the Aachen Cathedral Treasury, the Federal Ministry of Regional Planning, Building and Urban Development decided to erect a Test Bunker for the Protection of Artefacts. Because only a short journey could guarantee a safe transfer in an emergency, the cathedral chapter decided to build a new Treasury on the west side of the cloisters in the immediate proximity of the bunker. Planning and construction took place from 1975 to 1979. In 1979 the new exhibition room came into service. The items were exhibited to the public in chronological order in three rooms with a floorspace of 490 m2. In time, however, technical shortcomings presented themselves, which endangered the masterpieces. Therefore, a new arrangement was organised in 1995, to meet conservation, technical, and safety requirements.
