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.
The diagrams above show the condition of the structure and standard of maintenance in the listed historic buildings inspected as percentages of the total, and by category, in 2013.

Structure & maintenance 2013
Of the 5,860 listed buildings inspected in 2013, the structure was found to be ‘reasonable’ or ‘good’ in 97.2% (2,326). The standard of maintenance was ‘good’ or ‘reasonable’ in an average 87.4% of the buildings inspected, and ‘substandard’ to ‘poor’ in 12.6%.
Coverage differs between categories
The Register of Monuments and Historic Buildings has 13 categories of listed monuments and buildings. Not only does the condition of the structure differ between categories, so does the number of buildings inspected. When interpreting the results it is important to bear in mind the fact that the rate of coverage is not the same for all categories.
Most inspections in ‘buildings and houses’ category
The ‘buildings and houses’ category accounts for the largest proportion of listed buildings inspected (2,326, or 39.7% of the total). In 97.9% of cases the structure was ‘reasonable’ or ‘good’ in 2013; the standard of maintenance was ‘reasonable’ or ‘good’ in 86.3%.
The ‘agricultural buildings’ and ‘individual objects’ categories both had fairly sizeable proportions of inspected properties where the condition of the structure was found to be ‘substandard’ or ‘poor’ (8.5% and 6.4% respectively). Besides the ‘agricultural buildings’ category, the ‘road and water infrastructure’ and ‘defence works’ categories also had relatively large proportions of buildings in which the standard of maintenance was judged to be ‘substandard’ or ‘poor’, at an average of 15.2% to 18.3%.
Inspection data from National Monuments and Historic Buildings Inspectorate (Monumentenwacht Nederland), 2013
Monitoring frequency: annual
Since 2015 only data for the last year available have been shown in the above information. Data from previous inspections can however be accessed in the database.
The data for these indicators were collected by the National Monuments and Historic Buildings Inspectorate from the 11 provincial inspectorates. The picture that emerges from the data concerning the technical condition of listed historic buildings cannot be regarded as representative of all listed historic buildings. The data do however give a full and reliable impression of the technical condition of the listed buildings inspected, a not inconsiderable proportion of the total stock of listed historic buildings (approx. 9.5% in 2013), making it a valuable source of information. It is not however known to what extent the picture obtained is selective. In 2015 the RCE is conducting a study to establish the extent to which these data are representative of the entire stock of listed historic buildings.
The number of inspections performed by the Monuments and Historic Buildings Inspectorate differs from year to year, as do the buildings inspected. The number of inspections per province also differs, so the results can differ from one province to another. Any differences might also be related to the methods of assessment used in different provinces.
For further information on the data and the study, see the reports on the results of inspections in 2008, 2009 and 2010, under related publications. Since 2011 the results have only be accessible via erfgoedmonitor.nl (heritage monitor), and are no longer available in the form of reports.
