Frederiksberg Palace Gardens is one of the largest and most attractive green spaces in Copenhagen. The park was landscaped during the reign of King Frederik IV from 1699–1730, as a baroque garden surrounding Frederiksberg Palace. The gardens now house the remains of the baroque garden and a romantic landscape garden, which held special significance for the popular King Frederik VI. The romantic landscape garden was changed during his reign from 1808–1839.
Today, those wishing to sail along the canals like the king can hire boats from the boat service Svendsens Bådfart. In the summer, Frederiksberg Gardens form the setting for various cultural events, including the music festival Stella Polaris (August) and Midsummer’s Eve (June). Midsummer’s Eve is a particularly special evening in Frederiksberg, attracting some 35,000 visitors. There is a bonfire party by the water close to Frederiksberg Palace and entertainment aplenty.
