Lilleborg is a ruined castle in the Almindingen forest. The castle was probably built in the middle of the 12th century as a royal fortress. It appears to have replaced the much larger fortress of Gamleborg which was only 700 metres away. The move could be explained by the fact that in 1149, three-fourths of Bornholm had been surrendered to Eskil, archbishop of Lund. As a result, King Sweyn III wanted to establish his own seat of power on the remaining fourth of the island. While it could not be compared to the archbishop's Hammershus, Lilleborg was nevertheless a fine stronghold and appears to have been easier to defend than the much larger Gamleborg. There is evidence suggesting the fortress burnt down in 1259 when Prince Jaromar of Rügen stormed and destroyed the 'king's stronghold' on Bornholm. However, coins minted after that date have been found, indicating it was inhabited after its storming.
Lilleborg's construction inland rather than on the coast has been compared to that of Refshaleborg on Borgø in Maribo lake. It had a large tower, 9.5 metres square, protecting the entrance to the courtyard. Its walls were 2.4 metres thick and from the top it was easy to hit anyone trying to attack. The fortress is further protected by a curtain wall which follows the cliff tops around the oval plateau. The interior was some 76 metres long and 41 metres wide. When its defenses were obsolete, the fort's stones were re-purposed for other buildings. From 2006 to 2011, restoration work was carried out at Lilleborg.References:
The Jelling stones are massive carved runestones from the 10th century, found at the town of Jelling in Denmark. The older of the two Jelling stones was raised by King Gorm the Old in memory of his wife Thyra. The larger of the two stones was raised by King Gorm's son, Harald Bluetooth in memory of his parents, celebrating his conquest of Denmark and Norway, and his conversion of the Danes to Christianity. The runic inscriptions on these stones are considered the most well known in Denmark.
The Jelling stones stand in the churchyard of Jelling church between two large mounds. The stones represent the transitional period between the indigenous Norse paganism and the process of Christianization in Denmark; the larger stone is often cited as Denmark's baptismal certificate (dåbsattest), containing a depiction of Christ. They are strongly identified with the creation of Denmark as a nation state and both stones feature one of the earliest records of the name 'Danmark'.
After having been exposed to all kinds of weather for a thousand years cracks are beginning to show. On the 15th of 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.
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' gray and reddish tones and emphasising their monumental character and significance.
