Unfortunately, it sometimes happens that heritage buildings and structures unearthed during the construction of new infrastructures cannot be adequately conserved once dug out. Before the eternal doubt, keeping or covering them, the economic aspect often takes precedence. Luckily, when the decision is to hide it again, technology offers the possibility of acquiring, modelling and storing the 3D data of the remains and allows their later visualization with a very realistic appearance. Therefore, the memory of these remains destined to be forgotten survives beyond the archives of the professionals who documented them. In this paper, the opportunities opened by Augmented and Virtual Reality applications for the preservation and dissemination of re-covered, or even lost, remains will be explained through the finding came about in the works performed for renovating an old road in Fuente del Maestre (Spain)
