Aarhus Cathedral is Denmark's longest church and the tallest building in the city. Construction began in 1201, making it one of the oldest buildings in Aarhus, and the building was modified and extended over the following three centuries. The result is a mix of Romanesque foundations and Gothic elevations, with a remarkable collection of medieval frescoes covering the vaults and choir — more than in any other Danish cathedral.
The nave is long, light, and uncluttered; the effect is very different from the dark Gothic interiors typical of larger European cathedrals. An altarpiece by the sixteenth-century Lübeck painter Bernt Notke is the other major artwork in the building. The cathedral is in the centre of the old town, on the pedestrianised Bispetorv square.
