Tough tunnelling challenge in Italy

摘要

Pontremoli Magra, a town in the province of Massa-Carrara on the Tuscan side of the Apennines is the site of the Museum delle Statue Stele Lunigianesi (the Museum of the Stele Statues of Lunigiana) installed in the Piagnaro Castle dating back to the 1 Hh century. It is one of the most important collections of European pre-historic monuments and holds particular importance for their study. In response to the growing interest for the statues marked by an increase in visitors, the town of Pontremoli decided to improve access to the castle, reachable only by covering a distance on foot with a difference in height of 40m. The project, financed by the Regione Toscana, provides for a pedestrian tunnel accessible from a parking area adjacent to the town's historic walls.
