Another problem we discovered during inspection of the cellar was related to the base of the pillar carrying the lintel and part of the ceiling above the largest room. Similar to the cellar's vault-ceiling this base was weakened by long-term exposure to a humid environment. We therefore reinforced the base of the pillar with a concrete casing which now firmly holds it. The concrete casing will be supported by construction debris the whole cellar will be filled up with later on. This will provide the pillar with a sufficiently strong and stable base.
