Little is known of the Trinity Church, let alone its architecture, but despite its brief history at least two events are known to have taken place.
In Adam of Bremen's Gesta Hammaburgensis ecclesiae pontificum, there is an account of how the king's son, Sweyn Forkbeard, raised a rebellion against him, forcing him to flee to Jomsborg.
The cathedral is a major tourist attraction, bringing in over 125,000 visitors annually.
There is some doubt as to when Roskilde became the seat of the Bishop of Roskilde.When Sweyn Forkbeard conquered England in 1013, he began sending English bishops to Denmark, a process which was continued by his successor Cnut the Great.A working church, it also hosts concerts throughout the year.Roskilde was named the new capital of Denmark by King Harald Bluetooth around the year 960.The first Gothic cathedral to be built of brick, it encouraged the spread of the Brick Gothic style throughout Northern Europe.
Constructed during the 12th and 13th centuries, the cathedral incorporates both Gothic and Romanesque architectural features in its design.
When Bluetooth died in 985/986, the army that had been raised against him brought his body to Roskilde and buried him in the church he had built.
At Christmas in 1026, Ulf the Earl was murdered by one of Cnut the Great's housecarls.
This caused some conflict with the Archbishop of Hamburg, who regarded Scandinavia as belonging to the Archdiocese of Bremen.
The earliest known bishop of Roskilde was Gerbrand, who had been a cleric with Cnut the Great, and who was intercepted by the Archbishop of Hamburg-Bremen's men when he sailed to Denmark in 1022.
An à la carte menu of seafood dishes and sandwiches, as well as a weekend brunch are served at the in-house Restaurant Vigen.
