**Country:** Denmark

The UN/LOCODE DK CSO denotes Christiansø, a tiny fortress island in the Ertholmene archipelago about 18 km north-east of Bornholm and the easternmost point of Denmark. Its small, well-protected natural harbour — once the world's first naval base — now mainly handles the passenger ferry from Gudhjem and local fishing. With a fairway depth of only around 1.8 m, the island has no commercial cargo, container or breakbulk role. Forwarders with regional shipments use Rønne on Bornholm or Copenhagen instead.
