Roskilde Cathedral of St. Luke (Danish: Roskilde Domkirke), is in the city of Roskilde on the Island of Zealand (Sjælland) in eastern Denmark. It was the initial Gothic cathedral to be built of brick and its construction encouraged the spread of this Brick Gothic style throughout Northern Europe. It was constructed during the 12th and 13th centuries, and it incorporates both Gothic and Romanesque architectural features in its design. It was the only main cathedral in Zealand until the 20th century. The cathedral's identical spires dominate the skyline of the town.
The cathedral was built in a style of Romanesque characteristic of interior arches with half-rounded structure to sustain the flat interior ceiling. The foremost church has an extended nave and two side passageways. Two towers flanked the west front entrance. A three-sided stone monastery was constructed adjacent to the cathedral on the northern side of cathedral, for the monks and other associated people with the cathedral. Bishop Svend achieved success in bringing an important remnant, the skull of St. Lucius, an early pope (253-255), who later became the patron saint of the cathedral. The skull is now located in the Catholic Cathedral of St. Ansgar in Copenhagen.
From the beginning of 1987, the church has been the place of residence for one of Denmark's important boys' choirs, The Roskilde Cathedral Boys' Choir. The choir soon eminent its 20th centenary, which made a key resource in the parish youth work. All choristers’ boys go to normal school but meet up 2-3 times a week to rehearse. Every second year the choir of boys travels abroad destinations like New Zealand, Scandinavia, England, Greenland, France and Canada.
