The citadel in Copenhagen can now cope with a 1,000-year rainfall

The Ministry of Environment of Denmark and the Environmental Protection Agency, in collaboration with several other ministries, agencies and organisations have published a new case study on urban climate adaptation in Copenhagen. Seven cast-iron manhole covers on the ground are the only sign of extensive and very complex flood protection for the Citadel in Østerbro, Copenhagen. The fortification is a listed ancient monument. In recent years, the Citadel has been exposed to several torrential flood events following cloudbursts. Following major underground work, the Danish Defence Estates and Infrastructure Organisation has now secured the Citadel against a 1,000-year rainfall event.
