Several examples of recent damage to cultural heritage monuments due to natural disaster effects clearly show a very close dependence of the extent of damage on previous restoration interventions and on the healthy condition of the damaged monument (Drdácký et al., 2007). Z. Slížková analysed damage to historic objects in the Château Veltrusy Park near Prague which were severely
damaged by the flood in 2002. There was a remarkable difference between objects which had been properly restored before the flood, e.g. a stone bridge with Sphinx, and objects which were neglected or incorrectly restored, e. g. sculptures on the Château’s monumental stairs. Even though the bridge was totally immersed in a high water stream, it only needed to be cleaned with water and low pressure steam. In 2004, some hair cracks and slight mortar disintegration were visible in masonry joints. After the next flood in 2006 the bridge was only slightly restored (colour retouching, plaster repair). On the other hand, the sculptures were repaired long before the 2002 flood by applying Portland cement and polyvinyl-acetate consolidation, which substantially decreased the water and vapour permeability and kept the water inside the material. This increased the contamination with salts, biocolonization, surface detachment, and disintegration patterns
up to a height of three metres. Freezing, moisture dilation and crystallization damage required a very substantial restoration intervention after the flood.
