Odense

• 1. Introduction

  ›

  Odense carries a name that translates, from Old Norse, as "Odin's sanctuary." Centuries before any church rose on the island of Funen, people gathered here to worship the Norse god, and they left their mark in the soil. Archaeological excavations around the city have found evidence of continuous human settlement stretching back more than four thousand years, to at least the Stone Age. Long before Denmark existed as a nation, this patch of ground along the Odense River was already home.

  Today the city is best known the world over as the birthplace of Hans Christian Andersen, the storyteller who invented the Ugly Duckling and the Little Mermaid. But Andersen is only one thread in a far older cloth. Odense sheltered the last of the Viking kings, printed the first book in Scandinavia, and gave Denmark its second national television channel. A tower it built in 1935 was the second tallest in Europe before it was blown apart in the Second World War. Today the city hosts more than three hundred robotics and automation companies and nearly twenty thousand workers in that sector alone.

  How did a city on a Danish island, population roughly 185,000, accumulate so many first-and-only claims? The answer runs from Viking ring fortresses to a canal dug between 1796 and 1806, from a murdered king who became a saint to a fairy-tale writer whose museum was redesigned by a Japanese architect in 2021.

• 2. Odin's Town

  ›

  A letter dated the 18th of March 988, written by the German emperor Otto III, granted rights to Odense and its neighbouring settlements. That document is the first surviving written record of the city's name. The city celebrated its thousandth anniversary in 1988 based on that date, and to mark the occasion planted a forest called Tusindårsskoven, meaning "The Thousand Year Forest."

  The earliest community was not where the modern centre stands. It grew on higher ground between the Odense River to the south and Naesbyhoved Lake to the north, a lake that has since dried up entirely. To the south of the river lay Nonnebakken, one of Denmark's six former Viking ring fortresses, built during the reign of Sweyn Forkbeard. He had forced his father, Harold Bluetooth, out of the country and into exile around 975. The fort commanded the river approach; whatever came in from the coast had to pass beneath its walls.

  By the early 11th century the town had expanded into the area around Albani Torv, Fisketorvet, Overgade and Vestergade, streets that still carry those names. By 1070, contemporary sources record it as a city of stature in Denmark. The territory had been made a Catholic diocese in 988 itself, the same year as the Otto III letter, and the first recorded bishops were Odinkar Hvide and Reginbert, the latter consecrated by Archbishop Æthelnoth of Canterbury in 1022.

• 3. A King Killed in a Priory

  ›

  On the 10th of July 1086, inside St Alban's Priory in Odense, a group of peasants killed the king of Denmark. Canute IV, whom later generations would call the last Viking king, had imposed heavy taxes on the town, and the discontent had reached a breaking point. The priory itself no longer stands. A church has occupied that site since around the year 900, but the building where Canute died is gone.

  Canute was canonized in 1100, fourteen years after his murder, and his shrine in Odense Cathedral drew pilgrims throughout the Middle Ages. Under the altar of that cathedral, visitors can still view the skeletons of Canute and his brother, placed on public display alongside a large fragment of Byzantine cloth. The cathedral also holds one of Denmark's most remarkable altarpieces, a triptych carved by Claus Berg.

  Canute's death set off a chain of written memory. At the beginning of the 12th century, Benedictine monks from England founded St Canute's Abbey in Odense. It was there that the English monk Ælnoth wrote what is considered Denmark's first literary work: Vita et Passio S. Canuti, meaning The Life and Passion of St Canute. Kings Hans and Christian II were later buried in the city, continuing Odense's long entanglement with Danish royal history.

• 4. Print, Commerce, and Ruin

  ›

  In 1482, Bishop Karl Rønnov brought a German printer named Johann Snell to Odense. Snell produced a short prayer book called Breviarium Ottoniense, which scholars consider the first work printed in Scandinavia. Alongside it, Snell also printed De obsidione et bello Rhodiano, an account of the Turkish siege of the island of Rhodes.

  The city had already endured one violent interruption. In 1247, Abel of Denmark burned Odense during a conflict with his brother King Erik IV, and the cathedral had to be completely rebuilt. Despite that, the town recovered and was formally chartered in 1335. For the next few centuries, commerce drove the city: cattle sales generated enough money to fill the streets with fine half-timbered merchant houses. The city also became the meeting place of several parliaments, serving as the seat of Funen's provincial assembly until 1805.

  Prosperity ended abruptly in the late 1650s when the Swedish Wars concluded and heavy taxes were imposed. A long stagnation followed, lasting until the end of the 18th century. The city's population around 1700 stood at roughly four thousand people, a modest number for a place that had already been considered a city of stature six hundred years before.

• 5. Canals, Railways, and Growth

  ›

  Frederick IV ordered the rebuilding of Odense Palace in 1720, partly on the foundations of a 13th-century monastery. The main white Baroque wing, designed by J.C. Krieger with thirteen bays, was completed in 1723. The King's Garden alongside it was laid out to a French design by Johan Cornelius Krieger.

  The more consequential infrastructure came later. Between 1796 and 1806, an eight-kilometre canal was dug to connect Odense Harbour to Odense Fjord. It was 7.5 metres deep. The canal fundamentally changed the city's trading position, opening the port to larger vessels and pushing the population upward. By 1851 the city gates were demolished, and development pushed south of the river for the first time.

  Denmark's first modern water and gas works opened in Odense in 1853. A railway across Funen followed in 1865, and Odense became one of Denmark's largest rail junctions. Iron, metals, textiles, food and beverages all found homes in the expanding industrial quarters. By 1900 the city had 35,000 inhabitants, a tenfold increase over its 1700 population. The census of 1901 recorded 40,138 people, and growth continued rapidly in the decades that followed.

• 6. The Storyteller's City

  ›

  Hans Christian Andersen was born in 1805 in a small yellow house on the corner of Hans Jensens Stræde and Bangs Boder in Odense's old town. His father was a shoemaker. Andersen left as a teenager, but the city has not let him go. In 1908 that yellow house was opened as the Hans Christian Andersen Museum, documenting his life through artefacts connected to his acquaintances and travels. His childhood home on Munkemøllestræde, where he lived from the age of two until he was fourteen, became a separate museum in 1930. It contains his father's cobbling tools.

  Throughout the city, statues of Andersen's characters occupy street corners and parks: the Steadfast Tin Soldier, the Mermaid, the Shepherdess and the Chimney Sweep, the Toad, the Darning Needle, the Emperor's New Clothes, the Sea Horse, the Paper Boat, the Flying Trunk, and the Wild Swans. A statue of Andersen himself stands in Eventyrhaven, the Fairy Tale Park beside the cathedral. Louis Hasselriis sculpted it in 1888, showing the author with a book in hand.

  In 2005 the city marked the 200th anniversary of Andersen's birth, and in 2025 it marks the 150th anniversary of his death. The HCA House, designed by Japanese architect Kengo Kuma, opened in 2021. It incorporates Andersen's birthplace and a domed memorial hall featuring frescos by Niels Larsen Stevns. The celebrations for the 200th anniversary were not without controversy: former mayor Anker Boye was criticised for mismanaging the event, including allegedly signing a contract with Tina Turner for a show that resulted in a deficit of thirteen million kroner.

• 7. War, Towers, and Television

  ›

  Odinstårnet, The Odin Tower, was completed in 1935 as the second-tallest tower in Europe, surpassed only by the Eiffel Tower. Its height was 177 metres. Nine years later, in 1944, a Danish Nazi group blew it up. It was never rebuilt. A miniature model now stands in Odinsparken, near the site of the original.

  During the German occupation, Odense's general strike of August 1943 contributed to terminating the collaboration with the occupiers. The city's population passed 100,000 for the first time during the war years, reaching 103,107 in 1945.

  The postwar decades brought institutional anchors. Odense University was established by law in 1964, with teaching beginning in 1966. In 1988 a major national television channel, TV 2, began broadcasting from Odense on the 1st of October, ending the monopoly previously held by Danmarks Radio. TV 2 was fully taken into state ownership in 2003 and today operates six channels, broadcasting over 40,000 hours of television per year with about 1,000 employees. The Odense Steel Shipyard, opened by A.P. Møller in 1919 and once Denmark's largest shipbuilding facility, closed in 2012 after international competition made it unviable. The Lindø site has since been converted into the Lindø Industrial Park, now specialising in offshore component production.

• 8. Robotics and What Comes Next

  ›

  Universal Robots and Mobile Industrial Robots, both headquartered in Odense, are among the companies that turned the city into an internationally recognised centre for collaborative robots, known as co-bots. The cluster now includes more than three hundred robotics, drone and automation companies employing nearly twenty thousand people. The national Danish cluster organisation, Odense Robotics, coordinates the sector, and the University of Southern Denmark runs leading academic robotics programmes on its Odense campus.

  The University of Southern Denmark was formed in 1998 from a merger of Odense University, the Southern Denmark Business School, the Southern Engineering School, and the South Jutland University Centre. By 2012 it had roughly 26,000 students, making it Denmark's third largest university. Its Odense campus houses all faculties in one place, a deliberate choice that the university describes as supporting cross-disciplinary research.

  A project underway at the time of writing will physically connect the university campus to Nyt OUH, the new buildings for Odense University Hospital. The combined structure will cover 500,000 square metres, placing it among the largest buildings in Europe. The Odense River still runs through the city, the fjord still carries icebreakers between January and March, and the Tusindårsskoven forest planted in 1988 now hosts the annual Tinderbox music festival each summer.
