Græsholm is a small, uninhabited island in the Ertholmene archipelago, lying about 18 kilometres north-east of Bornholm and marking the easternmost point of Denmark. Together with its neighbours Christiansø and Frederiksø, it forms a striking landscape of bare granite rising from the Baltic Sea. While the two sister islands carry the marks of a seventeenth-century naval fortress, Græsholm serves an entirely different purpose: it is a strictly protected bird sanctuary where landing is forbidden. That very inaccessibility has made it one of the most important seabird breeding sites in Northern Europe. On its exposed rocky ledges nests the largest Danish population of auks – guillemots and razorbills – and in the summer months the air fills with their cries and the beat of countless wings. Eiders, gulls, terns and cormorants also gather here, and in recent years grey seals have settled on the surrounding skerries. From the ramparts and cliffs of Christiansø, visitors can watch the teeming bird life through binoculars from a respectful distance without disturbing it, while local guides share the story of the islands and their wildlife. The Ertholmene are administered under the Danish Ministry of Defence, and it is this undisturbed protection that allows such abundance to flourish. The terrain is low and windswept, shaped by the sea, with heather, grass and salt-tolerant plants scattered between rounded granite outcrops. The boat trip out to the Ertholmene from Bornholm's harbours is a memorable journey in itself, and although Græsholm cannot be set foot upon, the island's silhouette and its clamouring colonies remain among the most evocative sights of the Danish Baltic. A visit to the archipelago blends cultural history, rugged rock scenery and one of the country's most intense encounters with untamed nature – a place where the wild is still allowed the final word.
