The centre last year carried out various projects to preserve some of the ancient capital’s most treasured monuments, he said. Through co-operation with the Hue Sciences University, moss and algae had been removed from many sites, helping to protect both the vestiges and tourists at the same time. "Hue is typically wet and humid which makes it an ideal environment for moss and algae to flourish on the old stone buildings," Hai explained. "This damaged the relics and made the floor slippery.” The centre has applied various methods in the past such as getting local people to sweep away the moss and algae, but that was rather time-consuming and not particularly effective, he said. The Hue Science University's project to use nano technology involves active substances to ward off moss and algae without polluting the environment. The solution has been applied at relics like The Mieu and Dai Cung Mon to offer safer paths for tourists. Also last year, the centre planted 60,000 plants in the Inner Citadel Area, and would focus on caring for 5,000 bonsai and decorative plants at relic sites this year, he said. - VNS
