Christmas of 1624 marked the beginning of something big. King Christian IV signed the document “Regulation on Post Messengers”, and the Danish postal service was born. With eight fixed routes, the country's communication was organized and unified. Since then, the postal system has connected people, cities, and regions.Today, we can send messages across the globe in seconds, but once, reaching each other was a slow and challenging process. Fjords and straits were crossed by sailboats, row ferries, steamships, and iceboats. Over land, letters, parcels, and passengers were carried on foot, by horseback, and by stagecoach. The history of the post is not just about letters and parcels — it’s also about innovation, determination, and efficiency. For 400 years, the pursuit of faster and more reliable mail delivery has driven progress. From the clever design of the “Kuglepost” (ball post) to steamships, stagecoaches, Renault 4s, and electric vehicles — modes of transport have evolved with the times and technology. The goal has always been the same: to deliver news, joy, and concern quickly and safely. The story of the postal service is also a story of connecting people. About the invention of the stamp and the mailbox, which became an everyday fixture in Danish life. About the mail carrier, who for centuries has been the vital link between sender and recipient, between good and bad news. And so much more.We celebrate 400 years of postal history by highlighting the events, inventions, and means of transport that have connected Denmark since 1624.
