Maupertuis Expedition 290
International symposium in Torne Valley, Lapland
4–6 September 2026
What is the role of Maupertuis and his expedition in the history of science? What can we learn from the Age of Enlightenment 290 years ago? How does history live locally and how can it be kept alive? What kind of connections are there between the 18th-century Age of Enlightenment expeditions and today’s tourism?
The Maupertuis Expedition 290 Symposium will seek answers to these and other questions.
THIS YEAR marks a milestone in the history of science. It will be 290 years since the French degree-measuring expedition visited the Torne Valley, Lapland. In 1736–1737, it was empirically proven for the first time that the Earth is slightly flattened at the poles.
The measurement project was led by mathematician and scientist Pierre Louis Moreau de Maupertuis, whose identity and career were significantly influenced by the expedition to the far North. Later in his career, Maupertuis served as the director of the Royal Prussian Academy of Sciences in Berlin.
The expedition also left its mark on Europeans’ perception of the North. In addition to Maupertuis’s La Figure de la Terre, the keen-eyed travelogue Journal d’un voyage au Nord written by priest Réginald Outhier and the maps attached to the work painted a picture of the exotic North.
THE SYMPOSIUM will bring together European historians of science and literary scholars in Tornio from Finland, France, Germany, Switzerland, Sweden and England.
The program will consist of lectures, discussions and excursions to degree measurement points all the way to Pello.
The event is intended for experts as well as a general public. It is free of charge.
Register in advance
The symposium is a three-day event. You can either attend the entire event or pick the parts that suit you. The event is free of charge.
Please note that the number of participants is limited. To ensure access to the event, register in advance. Registration opens in June.
If there is enough space, you can also attend the lectures without registering. Participation in the excursions requires always registration.
Most of the symposium’s presentations and discussions will be held in Tornio.
