Anyone who takes a walk around Copenhagen is bound to run across one of the hundreds of concrete bunkers that were built to defend Danes from air raids during World War II.
There are a couple in the park near my house, huge slabs of grey concrete now partially covered by greenery. Many of the interiors have been renovated, and the bunkers are very popular with up-and-coming rock bands, who use them as soundproof rehearsal halls.
The bunkers were never used for their intended purpose.
The German occupying force rolled in by land, and Denmark surrendered almost immediately – the flat Danish landscape would have been no match for the powerful Nazi tank divisions of 1940. Denmark was occupied for more than 5 years.
Tomorrow evening – Monday, May 4, 2020 – many Danes will put a candle in the window to mark the 75th anniversary of the end of that occupation.
