Scientists are not always trying to invent new things, because there is a lot we can learn from history as well. For years, historians, archeologists, architects, geologists and engineers have searched the archives, researched the Rhône river and its banks, calculated the river flow, the strength of old constructions and modeled 3D designs of the bridge of Avignon in Southern France.

The Bridge of Avignon – in France, known as Pont Saint Bénezet or Pont d’Avignon – is one of the most famous historical bridges in the world. It was originally constructed in the 12th century. The bridge – over 900 meters / 980 yards long – led over river Rhône. After the construction, strong currents and spates of Rhône destroyed the bridge. It was re-built a few times until in the 17th century people gave up, letting the river claim its space.

The remaining part of the bridge on the Avignon side of the river can be visited even today.

The mystery the researchers are trying to solve is how the bridge was built in the 12th century. Modern technology, like drones, measurement devices, computers and 3D modeling applications are exploited by researchers who have pretty good idea how
