[4] The Copenhagen–Roskilde railway line was prolonged from Roskilde to the port city of Korsør by the Great Belt in 1856.

It was long thought that the construction company William Radford also designed the station in Roskilde[10] but it has later been established that the architect was J.F.

Facing the city centre, the front of the original station building is symmetrical with two short rectangular towers with flat roofs flanking the main entrance.

The facade was brought back to its original colouring, the roof and tunnels were renovated, elevators and automatic doors were installed, and the arrival hall received new paving and furnishings.

For the opening of the Copenhagen–Roskilde railway line in 1847, the Danish composer Hans Christian Lumbye composed the still popular Copenhagen Steam Railway Galop, a musical composition which faithfully recreates the sounds of a train chugging out of a station and grinding to a halt at the next stop and which traditionally ends with the cry "Next stop Roskilde - the train does not go any further".
