After having been exposed to the elements for a thousand years, cracks were beginning to show. On 15 November 2008 experts from
UNESCO examined the stones to determine their condition. Experts requested that the stones be moved to an indoor exhibition hall, or in some other way protected
in situ, to prevent further damage from the weather. In February 2011 the site was vandalized using green spray paint, with the word "GELWANE" written on both sides of the larger stone, and with identical graffiti sprayed on a nearby gravestone and on the church door. After much speculation about the possible meaning of the enigmatic word "gelwane", the vandal was eventually discovered to be a 15-year-old boy with
Asperger's syndrome and the word itself was meaningless. As the paint had not fully hardened, The Heritage Agency of Denmark decided to keep the stones in their current location and selected a protective casing design from 157 projects submitted through a competition. The winner of the competition was Nobel Architects. The glass casing creates a climate system that keeps the stones at a fixed temperature and humidity and protects them from weathering. The design features rectangular glass casings strengthened by two solid bronze sides mounted on a supporting steel skeleton. The glass is coated with an anti-reflective material that gives the exhibit a greenish hue. Additionally, the bronze patina gives off a rusty, greenish colour, highlighting the runestones' grey and reddish tones and emphasising their monumental character and significance. == Runestone of Harald Bluetooth ==
