Description: Restore North Italy Cathedral

1. Survey the damage. The first step is to survey the damage to the cathedral and identify the missing parts of the architectural feature. This can be done by using a variety of methods, including visual inspection, laser scanning, and photogrammetry.
2. Reconstruct the missing parts. Once the missing parts have been identified, they can be reconstructed using a variety of materials, including stone, brick, minerals and lime. The reconstruction process should be carefully planned and executed to ensure that the new parts are indistinguishable from the original.
3. Seal the architectural feature. Once the missing parts have been reconstructed, the architectural feature should be sealed with a water-based impregnator sealant. This will help to protect the feature from further damage and deterioration.
