Resumen
Historically, urban fountains have been underestimated to the point of not being considered worthy of conservation. The foregoing reason, together with the lack of sufficient archaeological data on this type of element in the Renaissance city, makes it necessary to document and carry out graphic research to correct this deficiency and establish the relevance of these constructions. The present work shows, through the concrete case method, the analysis of three Renaissance fountains from the Spanish city of Lugo and the importance of these elements as urban landmarks that marked the essential lines of the development of cities after the medieval period. It also analyses the work of their constructors, who belonged to a workshop of plumbers and master builders from the historical territory of Trasmiera (Cantabria) and who took their art throughout the Spanish kingdom.
