The Copenhagen Fire Department forms the largest municipal fire brigade in Denmark with some 500 fire and ambulance personnel, 150 administration and service workers, and 35 workers in prevention. The brigade began as the Copenhagen Royal Fire Brigade on 9 July 1687 under King Christian V. After the passing of the Copenhagen Fire Act on 18 May 1868, on 1 August 1870 the Copenhagen Fire Brigade became a municipal institution in its own right. The fire department has its headquarters in the Copenhagen Central Fire Station which was designed by Ludvig Fenger in the Historicist style and inaugurated in 1892.
