As the official turnout was announced, people cheered and clapped and a few even claimed tears.
Spontaneously, people started bouncing up and down, and a wave spread through the crowd.
That Italian voters would reject the resumption of the country's nuclear power programme was never in doubt. The worry for many was how many people would come out to vote.
A number of parties urged people to stay at home, the prime minister himself didn't vote, preferring to spend Sunday and Monday, the two voting days, at the beach and at the office.
He was hoping the votes would fail to pass the barrier of 50 per cent plus one of the electorate voting. Only when that figure was achieved does the result becoming legally binding.
He failed. The official turnout - 57.2 per cent, the highest in an Italian referendum in almost 20 years.
