Trinitatis Church is part of the 17th century Trinitatis Complex, which includes the Rundetårn astronomical observatory tower and the Copenhagen University Library, in addition to the church. Built in the time of Christian IV, the church initially served the students of Copenhagen University.
The interior was seriously damaged in the fire of 1728 but was rebuilt in 1731. The bases and capitals of the columns and arches were repaired. All wood furnishings were replaced, and the floor was covered with tiles from Öland. The reconstruction was in Northern Gothic-Baroque style. The church was rededicated October 7, 1731 and the remains of the university library were moved again. The furnishings were renewed with an altarpiece and pulpit by Friederich Ehbisch (1731) and a large Baroque clock (1757). The church was refurbished in 1763.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.
