Overseas Network, Aug. 14 - A pit 5 meters deep and 10 meters wide was spotted on the central road of Amien, capital of Somme Province, France, from the night of 11 to 12 local time.
According to the Parisian newspaper, at 6:40 a.m. on the 12th, Amien municipal police found a deep pit in front of a pub in Leon de Bowery Square in the centre of the city during their morning patrol. Municipal authorities immediately blocked the area in order to avoid a more serious collapse of the road, cut off water, electricity and natural gas, and evacuated three nearby residents. A 2-metre fence will also be set up to prevent curiosity from approaching the pit.
Experts believe that the deep pit was formed by the collapse of a medieval cellar. Technicians will use cameras to detect the cellar environment on the 16th. The results will be helpful for road repair and follow-up works.
In order to find out the cause of the accident, experts consulted a large number of files and found that there was an underground cave dating back to the 14th century, which should be a medieval cellar. Many medieval cellars have been found in other parts of Amien, belonging to the Roman-Gaul relics.
The city government of Amien said in a communique that the high temperature this summer may cause ground movement, making the cellar structure fragile, and leakage of water supply system was also found at the site of the collapse. Amien Mayor Brigitte Frey said he was glad no one was injured in the accident.
