Another problem we discovered during inspection of the cellar was related to base of the pillar carrying lintel and part of ceiling above the largest room. Similar to cellar’s vault-ceiling this base was weakened by long-term exposure to humid environment. We therefore reinforced 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 sufficiently strong and stable base.
