Heritage registers in Belgium include immovable heritage such as World Heritage Sites, and National heritage sites, but also intangible cultural heritage. The agency responsible for keeping and updating inventories of immovable heritage is dependent on the region, as is the name for the object, which is called Beschermd erfgoed, Biens classés or Kulturdenkmal depending on the language of the municipality of the location.

In 1835 the Commission royale des monuments et des sites (Royal committee for monuments and sites) was created to advise the government on conservation and historic preservation. This committee was split in 1968 into a Flanders committee (Koninklijke Commissie voor Monumenten en Landschappen) and a Wallonian committee, and in 1993 a third committee was formed to administer the area of Brussels.

In the Walloon region, the organization of the European Heritage Days and the classification of objects is done by the Agence wallonne du Patrimoine (AWaP)

The German-speaking Community of Belgium, part of the area known as "East Belgium" also hosts the European Heritage Days, and calls them "Tage des offenen Denkmals".^[2] The heritage protection of East Belgium falls under the jurisdiction of Liège province.
