Søndermarken is one of Copenhagen's most atmospheric green spaces, a Romantic landscape park stretching across the Frederiksberg district just south of Roskildevej. Together with the adjoining Frederiksberg Gardens, from which it is separated only by the road, it forms part of a historic parkland once attached to Frederiksberg Palace, whose baroque silhouette rises on the hill opposite. Laid out in the late 18th century and reshaped in the English landscape style, Søndermarken trades formal avenues for gently rolling lawns, curving gravel paths, and stands of mature beech, oak, and lime that turn gold in autumn. The mood is calmer and more informal than its grander neighbour—this is a park for slow walks, picnics on the grass, and quiet reading beneath old trees. Beneath the lawns lies the park's most surprising feature: Cisternerne, a vast subterranean reservoir that once held Copenhagen's drinking water. Its cathedral-like chambers, where stalactites drip from vaulted ceilings and water mirrors the darkness, now host acclaimed contemporary art installations and light works that draw visitors from across the city. Emerging back into daylight, you rejoin a landscape dotted with monuments, wildflower meadows, and open glades where locals jog, walk dogs, and let children roam. Søndermarken is easy to reach from central Copenhagen and pairs naturally with a visit to Frederiksberg Gardens, the palace, and the nearby zoo. Spring brings carpets of anemones and blossom; summer fills the lawns with sunbathers; autumn sets the canopy ablaze; and even winter has its charm, when frost outlines the bare branches and the cisterns offer a warm, otherworldly refuge underground. Free to enter and open to all, it remains a beloved retreat where history, nature, and art quietly overlap—a green lung offering respite just minutes from the busy streets of Frederiksberg and the heart of the Danish capital.
