In the historic cellar vaults of the Warleberger Hof a small show on the history of the listed building and the preindustrial history of Kiel can be seen.
For the first time, the piece of an oak disk is revealed, which was discovered during the construction work in the Warleberger Hof. The spectacular find was made during the excavation works for the elevator of the city museum and was part of the foundation for a predecessor building. After dendrochronological investigations the wood piece could be dated to the year 1278. This proves that shortly after the foundation of the city, a stately building had been erected on the privileged grounds in direct proximity to the castle and the Danish Gate.
