Hildesheim Cathedral Museum, Religious art museum at Hildesheim Cathedral, Germany

Hildesheim Cathedral Museum is a sacred art museum in rooms adjacent to the Cathedral's southern transept, displaying artworks spanning from the Middle Ages to modern times. The collections include crosses, reliquaries, liturgical vessels, and ancient manuscripts from different periods.

Bishop Eduard Jakob Wedekin (1796–1870) turned the cathedral treasury into a diocesan museum, bringing Gothic works from parishes and his private collection into it and organising their proper storage and display. From 2010 to 2015 the museum was enlarged and completely redesigned during the cathedral renovation: the deconsecrated St Antonius church and parts of the cloister were added, growing the exhibition space from 200 to 800 m². It reopened on 17 April 2015, showing the Renaissance cathedral rood screen in a new building and the Bernward wall uncovered in the basement.

The collection displays sacred artworks that reflect regional religious practices and devotion across centuries. Visitors can see crosses, manuscripts, and vessels that held meaning in daily worship and ceremonial life.

Access is through the Cathedral foyer and guided tours are available to help understand the collections. It is helpful to allow time to explore the different rooms and their contents at a comfortable pace.

A tapestry called Artemisia from the 18th century received its own exhibition room after extensive restoration. These wall hangings display detailed scenes and represent a valuable part of the collection.
