In 1702, there was an extensive renovation and restoration project that was undertaken after another city-wide fire. During the renovation in the 1880s, under the direction of architects Christian Christie and Peter Andreas Blix, the Rococo interiors were restored to their former medieval appearance. As part of the Second Anglo-Dutch War, the 1665 Battle of Vågen took place in the main port area of Bergen. A cannonball from the sea battle between the English and Dutch fleets remains embedded in the cathedral's exterior wall. The present organ at Bergen Cathedral, by Rieger Orgelbau, is from 1997. The organ is the fifth one in the cathedral's history; the first known organ was installed in 1549. The cathedral is used regularly for musical concerts.
