Domschatzkammer Cologne, Medieval treasury museum in Altstadt-Nord, Germany.
The Treasury Chamber is a museum beneath the Cathedral that displays religious objects and liturgical items spanning many centuries. The two floors present precious reliquaries, textiles, and church treasures from different periods side by side.
The collection grew over centuries through donations and acquisitions that document the Cathedral's wealth and importance. Its holdings span from the early Middle Ages to modern times and show how religious practices changed.
The space reflects the veneration of the Three Kings, a devotion that shaped the city and appears throughout the displayed objects. Visitors see items that expressed this faith across centuries.
Access is through the Cathedral, so plan time to make your way down to the museum level. It is best to check ahead whether the Cathedral has scheduled services or special hours that might affect your visit.
Among the displayed items are medieval vaulted cellars that show how these underground spaces have been used for centuries. A visit gives you a glimpse into a hidden layer of Cathedral history that otherwise remains invisible.
