Zealand
The city spreads across Zealand, Amager and the little islet of Slotsholmen, where Christiansborg Palace stands.
Q 02How many islands make up the Danish archipelago beyond the Jutland peninsula?
406
Only about seventy of them are inhabited, and no spot in the whole country is more than 52 km from the sea.
Q 03Denmark's highest natural point, Møllehøj, rises to roughly what height?
171 m
For years the title was thought to belong to nearby Yding Skovhøj until a 2005 survey found Møllehøj was nine centimetres higher.

Germany
The border runs just 68 km across the base of Jutland; everything else is coastline.
Q 05No point in Denmark is farther from the coast than about how far?
52 km
That is roughly a one-hour drive, which helps explain why Danes have been sailors, traders and Vikings for a thousand years.
Q 06The island of Bornholm lies about 150 km east of the rest of Denmark, in which sea?
Baltic Sea
It is closer to Sweden and Poland than to Copenhagen, and its round churches and smoked herring make it a favourite summer escape.
Q 07What is Denmark's average height above sea level?
31 m
The country is a glacial leftover of moraine and sand, which is why cycling everywhere is so painless.

Q 09The Danish monarchy, the world's oldest still reigning, traces its roots to which 10th-century king?
Gorm the Old
His son Harald raised the Jelling stones in memory of Gorm and Queen Thyra, and every Danish monarch since descends from him.

Jelling stones
The larger stone, sometimes called Denmark's birth certificate, carries the oldest known image of Christ in Scandinavia.
Q 11An engineer at which company proposed the name Bluetooth in 1997?
Intel
Jim Kardach picked it because Harald united the Danish tribes and the technology was meant to unite communication protocols; the logo merges the runes for his initials.

Six
They were laid out with geometric precision in the 980s, and five of them became a UNESCO World Heritage Site in 2023.

1849
The date is still Constitution Day, and it also established lasting freedom of the press.
Q 23In the 1864 Second Schleswig War, Denmark lost Schleswig and Holstein to which powers?
Prussia and Austria
The defeat cost Denmark about a third of its territory and turned it into a small, neutral state overnight.
Q 14Which Danish king conquered England and ruled it, along with Denmark, in the early 11th century?
Canute the Great
His North Sea empire held together for almost thirty years, and the story of him ordering the tide back was meant to show his humility, not his arrogance.

1944
It happened while Denmark itself was under German occupation and in no position to object.
