ABSTRACT
This paper analyzes and discusses the possibility of using the concept of intangible heritage in sets of infrastructures carried out under previous planning in the Spanish and Spanish America territorial framework. For this, a compilation of the different aspects related to heritage has been made regardless of the area of application: protection, conservation, legislation, restoration, etc. The concepts of public works and heritage are analyzed in relation to their social function and their historical value. The architectural, historical or landscape elements which characterize public works classified as heritage are examined and it is proposed to add the social function as another characteristic element of them. Finally, a notion of intangible heritage is developed as since it helps to propose the protection of sets of public works planned under specific political actions. Likewise, the proposal is illustrated with the case of the planning of hydraulic works in 18th century Spain. This planning explains and frames a large collection of hydraulic works that belong to a specific reformist and Enlightenment hydraulic policy. Therefore, it is concluded by justifying the concept of intangible heritage for certain infrastructure plans.
