Tallinn Town Hall, located in the main square, is the only surviving Gothic town hall in Northern Europe. The first recorded mention of the Town Hall dates from 1322. Its present form dates from 1402-1404, when the building was rebuilt. The spire was destroyed in an aerial bombing on March 9, 1944. It was rebuilt in 1950. The Town Hall is in the list of UNESCO World Heritage Sites with the Tallinn's Old Town.
The building has two main storeys and an almost full-sized cellar. The main façade is supported by an open arcade with eight piers and topped by a crenellated parapet. High gables and a pitched roof make the building elegant, but the slender octagonal projecting tower with a gallery for bells gives it particular finesse. The tower is crowned by a late Renaissance spire comprising three cupolas and open galleries.
Today the Town Hall is a representative building of Tallinn City Government, concert hall and museum. The entire building is open to the public in July and August, when less official receptions are held. In other times, visits must be agreed with the Town Hall in advance (except the cellar exhibition).
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.
