The cold weather also left buses struggling to drive up the Italian capital’s slushy hills, and cars without tyre chains were temporarily ordered off the road. Scores of vehicles were blocked for hours on the ring road around the city after cars skidded and crashed.
Drivers frustrated at waiting for accidents to be cleared ended up abandoning their cars.
About 6cm (2.5in) of snow fell in many areas of the capital.
Authorities stopped visitors from entering the Colosseum, the adjacent Roman Forum and the Palatine Hill, the former home of Rome’s ancient emperors. However, those already inside the ruins before heavy snow began coming down were allowed to finish their visits. The north of Italy was hit far harder than Rome, with a snowstorm dumping about 40cm (3ft) of the white flakes. Authorities appealed to Italians to avoid unnecessary travel, as the cold spell was forecast to continue well into the next week.
The last substantial snowfall in Rome occurred in 1986, though lighter snowfalls have occasionally and briefly blanketed the city since, including in 2010. In Bosnia, huge snowfalls trapped people in their homes and cars, and even prevented the presidents of neighboring Serbia and Croatia from getting home from a summit.
More than a metre (3ft) of snow fell on the capital, Sarajevo, trapping most people in their homes, and about 30 people spent the night in their vehicles in a tunnel south of the city.
At least 122 people have died in Ukraine as a result of the bitterly cold weather that has swept the country over the past week, the emergencies ministry said. Twelve people had died in hospitals and 32 in their homes while 78 had succumbed to the cold on the streets, it said. More 3,000 shelters have now been set up to provide people with warmth and food.
