According to the National Plan for Industrial Heritage, “movable and immovable property and
social systems related to the culture of work, must be understood as a whole composed by the
landscape in which they are integrated, the industrial relations in which they are structured, the
architectures that characterize them, the techniques used in their procedures, the files
generated during their activity and their symbolic practices”. In many cases, machinery of the
manufacturing processes subsists in the industrial building. Other times, due to the
independent nature of movable property, they acquire a particular obsolescence and fragility.
Our case study is one of the original ""artifacts"" of the Industrial Heritage of Castilla y León,
specifically, the mallet of the first lock of the Canal de Castilla, ""the mallet of Alar del Rey"". In
order to recognize and dignify both, the industrial building and its integrated movable
properties, it has been necessary to analyze the machinery of similar industries to formulate
hypotheses about its form and function. Likewise, to proceed with the analysis and graphic
reconstruction, it has been essential the help of graphic and written documents.
