The cathedral, a UNESCO World Heritage Site since 1985, has a fascinating history of transformations. Initially converted and expanded during the 11th, 12th, and 14th centuries, it was thoughtfully rebuilt after its unfortunate destruction in the fifties. Among its most renowned features are the 1,000-year-old rose bush near the apse and the exquisite Bernwardinian bronze casts: the double-winged Erztür from 1015 and the Christussäule from 1020. When visiting, take a moment to appreciate the intricacy of these ancient masterpieces. The Erztür, with its detailed biblical scenes, offers a glimpse into the artistry of the medieval era. Meanwhile, the Christussäule stands tall as a testament to the craftsmanship and religious devotion of its time. Imagine the generations of people who have marveled at these works. The cathedral is not just an architectural wonder, but a living piece of history, whispering stories of the past to those who walk its halls.
