At one point the water in the central part of Venice
was 1.56m above sea level.
It hasn't been that high since 1986.
Venice gets regular flooding at this time of year
but this was the fourth deepest on record.
Dozens of homes and businesses were inundated.
Scores of people had to move out,
though there are no reports of serious injuries.
With mopping up still underway,
the authorities say they don't yet know the final cost of repairs.
They've appealed to the government for money from a special fund
to help in the clear-up.
The all-time record for high water was in 1966
when it reached nearly two metres.
The city then suffered widespread
and devastating flooding.
