Naours Underground City
Highlight • Other
Fallen into oblivion in the 19th century, the underground city will be rediscovered in 1887, studied from an archaeological point of view and then opened to visitors.
An important occupation during the Thirty Years' War has been attested by archeology1.
This underground city could shelter nearly 2,000 people. Throughout the galleries are the rooms of the different families. Also noticeable are the stables with the troughs, the ventilation chimneys and the smoke chimneys which stood out in those of the houses.
Almost everywhere on the walls there are inscriptions, religious symbols, etc. with dates ranging from the year 1340 to 1792.
It was finally used by British soldiers during the Second World War.
The visit is worth the detour!
