Big cities have bad crime rates. But some have something else in addition.
Though there are several metropolises that can boast nasty areas and sketchy streets some cities can boast a little bit extra. War, terrorism, ethnic tension and rioting are all factors that we took into account when looking to find Europe’s most dangerous cities.
We also had a little look at some statistics on quality of life provided by Eurobarometer to give us a clue where the nastiest places to live, or even visit, are on the continent.
Overall we came up with the following places. Some of them are indisputably dangerous places to find yourself. In others, the danger is hid under the surface manifesting itself through organised crime.
Nevertheless, maybe it’s best to be vigilant if you find yourself in one of these places.
Almost a third of Sofia's residents say that they never feel safe in the Bulgarian capital.
Though crime reportedly dropped in 2010, the levels of robbery and theft still remain high.
However, the most worrying aspect about Sofia is its organised crime. In 2010, a local radio host was assassinated in broad daylight. One of the men responsible, a prominent Bulgarian gangster was taken into custody but later released when no one was willing to give evidence against him.
This prompted Bulgaria's interior minister to publicly state that for the past 20 years, prosecutors have had to bow to the wishes of some 300 gangsters in the city.
In 2009, the U.S. Embassy in Sofia released a list of 140 contract murders in the city that had been committed between 1993 and 2008. No high level crime bosses had been committed for any of the crimes.
If all this wasn't scary enough, the city is now experiencing rioting as the Bulgarian population violently demonstrate against Roma gypsies.
In fact, only 20 per cent of Sofia's residents say they feel safe all the time.
A city divided between Serbs and Albanians, Mitrovica is constantly brimming with tension between the two demographics.
Past conflict between the two groups was brutal and a large number of NATO peace keeping troops are still present in the city today.
When Kosovo declared independence in 2008, the city's Serbian population refused to recognise rule of the ethnic Albanian authorities or respect Kosovan rule. Incidents between the two groups occur regularly.
Just this week, a group of masked Serbs reportedly attacked a group of Albanians as they worked by the Ibar river, which divides the city's two populations. It wasn't the only disturbance, Albanians attacked Serbian cars and police had rocks thrown at them.
More NATO peacekeeping forces have been called for as the European community begin to worry that tensions in the city are the worst they've been since 2008.
Once hailed as the murder capital of Western Europe, Glasgow still has high rates of violent crime.
In 2003, it was reported that the city had the most violent crime in the UK as knife crime was on the rise. By 2005, Glasgow was said to have as much violent crime as Rio de Janeiro. In 2008, the city was said to have more violent crime per capita than in New York City.
One traditional welcome in the city is the 'Glasgow kiss' which is, essentially, a glorified headbutt.
Things are looking up however, a recent initiative in the city reduced violent activity by 50 per cent in those who participated. Only in those who participated though.
Compared to the murder capital of Western Europe, or a city divided along ethnic lines, Marseilles may appear a bizarre choice for the list.
However, France's second largest city is another metropolis deeply affected by organised crime based on drug feuds and turf wars.
From a prominent drug lord known as the Gremlin (who was shot down in 2006) to a mysterious pimp going by the Belgian (who was shot down in 2000, common theme here) turf wars on the streets of Marseilles have been bloody since the 1970s.
Not that the violence is confined to Mafiosos. Argentinian soccer player Lucho Gonzalez begged the city's soccer team to let him leave the club when thieves broke into his home, threatening him and his girlfriend while making off with jewelry and a Bentley.
Couple this with the fact that the deadly Portuguese Man O' War has been starting to populate the Mediterranean sea in recent years, and things don't seem so great in southern France.
Following conflict with Russia in 2008, there are large parts of the Georgia that you'd still be advised to stay away from.
In the capital, Tbilisi, violence still springs up and disturbances are often met with force. In may, riot police were deployed on political protestors leaving 40 injured and two dead. Georgian authorities denied using excessive force.
In 2008, following the country's presidential elections there was mass violence, described as the worst in the nation's post-Soviet history. Eight people died, 150 were left wounded.
However, an isolated incident isn't what earns the city its place on the list. In past months, external news sources have documented Armenia's and Yerevan's reputation for domestic violence, something that appears to be taboo in the country.
A 2008 survey by Amnesty International showed that three out of 10 women suffered from domestic violence. A United Nations study in 2010 noted that only 15 per cent of those abused were willing to talk about it.
The city is trying to save its image, however. This month, the city hosted a discussion on Armenia report of the European Committee for the Prevention of Torture and Inhuman or Degrading Treatment or Punishment.
39 per cent of Istanbul's residents say they never feel safe. Only 20 per cent of its inhabitants ever feel safe.
Furthermore, almost 60 per cent of people say you can't trust anyone in the city. But, even given these statistics there's still more to fear in Turkey's largest city.
Terrorism has affected the city badly in recent years and has persisted for many years. The country as a whole faces threats from al-Qaeda and Kurdish separatist among other groups and Istanbul has been hit badly in recent years.
This Spring, eight people were injured by another blast.
Regarded as the most crime laden city in Italy, even those born in Napoli regard it as a violent and unpleasant metropolis.
One blog, written by a proud (or not so proud) Neopolitan says that the city's inhabitants 'are the vilest, lowest dreck on the face of the planet and to call them beasts insults beasts.'
The city has a strong mafia link. Recently, when Italian soccer star Mario Balotelli visited the city, he was reportedly greeted and given a tour by a prominent mafia boss.
21 per cent of residents say they never feel safe, while over a quarter of the city's inhabitants should apparently never be trusted.
Much of Chechnya is extremely dangerous, but Grozny has recently made top 10 lists of the world's worst cities, so we'll include it here.
Heavily impacted by war during the early parts of the last decade, it was named the most destroyed city on earth by the United Nations in 2003. The city has been subject to missile attacks, shelling and bombing over the course of two wars.
One source states that during the first Chechen war, between 1994 and 1996, an estimated 20,000 (if not more) people were killed. Another 5,000 were killed during the second Chechen war in 1999.
Though the city is beginning to rebuild, it is still largely destroyed and many live without basic amenities. That's if they haven't left the place.
It's also run by some nasty pretty nasty folk. Ramzan Kadyrov, the most prominent figure in the city and the Chechen leader, counts Mike Tyson as a close friend and owns a pet leopard and tiger. And a few guns.
