By  architectural heritage  It can be understood a building, a group of buildings or the ruins of a building or a group of buildings that, with the passage of time, have acquired a value greater than that originally assigned and that goes far beyond the original commission. This value, as the chapters of  ICOMOS can be cultural or emotional, physical or intangible, historical or technical.

The works of architecture that can be considered architectural heritage will then be those that, due to a multiplicity of reasons, not all of a technical or artistic nature, are considered that, without them, the environment where they are located would cease to be what it is.
