In 2013 the Monuments and Historic Buildings Inspectorates performed 5,860 inspections on listed historic buildings. Most were in the ‘residential’ category (2,326). In this category, the structure of 97.9% of the buildings was in reasonable or good condition, and the standard of maintenance was reasonable or good in 86.3% of cases.
A trend has been established for the scores of listed buildings inspected on more than one occasion. In 47.2% of buildings inspected on multiple occasions the standard of maintenance remained the same, in 31.1% it improved and in 21.7% it deteriorated. The standard of maintenance of ‘road and water infrastructure’ and ‘defence works’ deteriorated slightly in relative terms.
A trend has been identified for historic buildings that have been inspected three times or more. In 70.3% of buildings inspected on multiple occasions the condition of the structure has remained the same, in 21.2% it has improved and in 8.6% it has deteriorated. The structure of ‘road and water infrastructure’ and ‘defence works’ deteriorated less than in the other categories.
At the end of 2018 there were 61,908 listed buildings in the Netherlands. Since 2007 the focus has been on the post-war reconstruction period.
At the end of 2018, over half (58.6%) of the items on the Register of Monuments and Historic Buildings (61,908) were objects in the category ‘Buildings and houses’ (36,252).
Generally speaking, most newly listed archaeological complexes are from more recent periods. The Neolithic-Bronze Age (1,010) is an exception, with a large number of protected barrows from this period.
