Thousands of parties on the street and fireworks were depicted by the city while Napoli won the Serie A Glorie.
The side of Antonio Conte beat Cagliari 2-0 last night in the Stadio Diego Armando Maradona to pipper Inter Milan to the title.
Napoli celebrated the fourth scudetto of the club in style when wild festivities continued until the next morning.
The stunning atmosphere started hours before the kick -off when supporters without a competition ticket to the most important Piazza del Plebiscito of the city ran to watch the match on large screens.
Incredible videos showed thousands that fill the huge square within a few minutes when others gathered outside the stadium.
Fireworks were lit in Naples when Scott McTominay scored a shameful bicycle kick to put them 1-0.
Smoke from torches flooded the Maradona Stadium and the field could hardly be seen on TV.
Romelu Lukaku then sealed the title with a beautiful solo goal when the party really started.
Even more fireworks and torches were released because amazing images from the mountains with a view of Naples demonstrated the place.
As far as the eye could see, there were lively flashy lights while the city obsessed with football was looking forward to it.
Fans remained stunned by the images, saying one: “The only thing that didn't burst is Mount Vesuvius.”
Another added: “Best fans in Italy and the home of the most iconic football player in history. Diego would be proud.”
A third surprised: “Scenes. They know how to celebrate.”
The joy extended to Milan when hundreds of Napolitans arrived late last night before the Cathedral of Duomo.
During the last whistle, Napoli players threw Conte in the air while he and club president Aurelio de Laurentiis then shared an emotional hug and were close to the tears.
However, fans were left in anticipation, because the manager was forced to do his press conference after the game for the trophy lift.
But the Napoli team Gatrashte the interview and drove him in Champagne.
Each member of the team then painted their hair blue and an honorary guard from the tunnel to the stage was formed by members of the back room staff.
Players appeared a front one from the dressing room when their name was called and they were all by the crowd of Serenade.
Serie A player of the MCTominay season received one of the biggest receptions and completed a remarkable turning point since he left Manchester United last summer.
The Napolitan party went on for a long time, while hundreds of banners with number four above the iconic narrow streets in the Quartieri Spagnoli district were hung.
Mctominay is called the “Darling of Napoli” after he was one of the most important men of the team on his way to Serie A Glory.
There are shrines everywhere in Maradona-style, flags and kits in the city based on the Scottish midfielder who signed only £ 25 million a year ago.
