A building in the Old Town in Geneva has been evacuated due to mysterious movements.
The 14th century house has 12 apartments - all those living there are not allowed to return until engineers have given the all clear.
It was built in the year 1360 - and used to house a hospital towards the end of the medieval period.
Residents were alerted to the movement after an ancient beam broke and cracks appeared in the walls.
The problem for the experts is that they don’t really know how it was built - or what walls are load bearing.
The study could take several days to determine the problem.
