According to an old legend the Thousand-Year-Old Rose Tree, which surrounds the apse of the Cathedral, marks the location of this holy place, to which the city and diocese of Hildesheim owe their existence.

The Cathedral, initiated by bishop Altfried in 872 and completed by bishop Hezilo in 1061, was rebuilt in her original shape after being severely damaged during World War II.

The medieval furnishing of the Cathedral with crowns of light, relic shrines and bronze font is unique in Europe.

Especially the two monumental bronze works dating back to the early 11th century, the pillar of Christ and the Bernward door, constitute exceptional artistic achievements.
