It may boast the Trevi Fountain, the Spanish Steps, and the glories that were ancient Rome, but the city is now in chronic decline, its business leaders and inhabitants have warned.

The Eternal City is facing crisis, with its administration engulfed in corruption scandals and debt, its roads scarred by potholes, the main airport partially closed, and a growing immigration crisis.

For generations the Italian capital has rested on past glories rather than built on them, but now its multiple problems have come to a head.

Drivers on the metro system are on a go-slow in a protest over pay and conditions, hundreds of flights into Fiumicino, the main airport, have been canceled because of a fire that broke out in a terminal back in May, and temperatures have soared this week to over 100 degrees Fahrenheit (37.7 Celsius), making daily life even more hellish than normal.

"Rome is on the verge of collapse," Giancarlo Cremonesi, the president of the Rome Chamber of Commerce, told Reuters.

"It is unacceptable that a major city which calls itself developed can find itself in such a state of decay."

A survey by the European Commission two years ago placed Rome last out of 28 European Union capitals in a ranking for the efficiency of city services.

Despite great food, superb coffee, and an enviable climate, on an index of quality of life, the capital came second to last, with Athens at the bottom.

Everything has been exacerbated by the effects of Italy’s longest recession since World War II, with homeless people on the street and youth unemployment over 40%.

Broken-down motor scooters and bicycles are dumped on pavements, curbs are overgrown with grass and shrubs, and there is litter everywhere.

A lack of bins mean locals and visitors alike drop their garbage on the ground, while a much-hyped bike-sharing plan that was launched a few years ago has broken down entirely, the bicycles either damaged or stolen.

"It has got a lot worse in the last few years," Costanza Cagni, who has lived in the city since 2000, told The Telegraph.

"Everybody moans, but nobody offers any solutions. The quality of life has really gone down. I'm sorry to say it, but I just want to leave Rome and move somewhere else."

The city was hit by a major corruption scandal earlier this year that explained, in part, why public services are so shoddy.

An investigation found that corrupt local politicians had colluded with criminal gangs to cream off money from a range of services, from trash collection to the management of refugee facilities.

The scandal has been dubbed "Mafia Capitale," and it comes amid growing evidence that the city is being infiltrated by organized crime groups.

The crime syndicate is believed to be laundering more and more of its money through legitimate businesses in Rome, as well as Milan.

Exploitation by criminal gangs has exacerbated years of incompetent administration by the city council.

Ignazio Marino, a former surgeon who is now mayor of Rome, acknowledged that much of the city’s public administration was "substantially rotten."

In an open letter this week to Corriere della Sera, a leading daily, he said that like Matteo Renzi, the prime minister, who is trying to push through difficult reforms at the national level, he too was trying to implement "profound and radical reforms" in the capital.

He said he had come up against a "cancer" of favoritism and deep resistance to change. But as he wages that fight, historic buildings remain daubed with ugly graffiti, with the culprits hardly ever caught.

"It's a combination of bad administration, corruption, and bureaucracy. The metro hasn't worked properly for the last 15 days. If that was the case in London, you would have a public revolt on your hands."

Rome needed a leader such as Rudy Giuliani, the former mayor of New York, who in the 1990s cleaned up the metropolis with a regime of zero tolerance, drawing on the "broken-windows theory," which held that if minor violations were tolerated, much more serious crimes would flourish.

"If someone parks illegally or urinates in the street, they need to be fined," Tonelli said. "We need to tackle egoism and individualism, the idea that it is every man for himself."

Garbage, bad transport, and graffiti harm tourism — each year the city attracts around 10 million visitors, but the rate of repeat visits is among the lowest in Europe.

"We need a complete change of mentality," Tonelli said. "New York in the '90s was very similar to how Rome is now — there was corruption, it was dirty, nobody paid when they traveled on the metro, there was graffiti. It can be done. It is not irrecoverable."
