苏格兰将于明年9月18日举行公投，决定是否结束与英格兰长达三个世纪的联合，成为独立的国家。在距离公投还有一年的时候，苏格兰的四位工匠却已着手开始修复曾经阻隔双方的边境墙——哈德良长城。哈德良长城是罗马帝国在占领不列颠时修建的，当时主要是为了阻止“野蛮”的苏格兰人进入“文明的”英格兰。此次修复工程主要是为了保护历史遗迹，由哈德良长城信托基金出资，工程有望在下月底完工。不过，参与修复的工匠笑称，如果明年公投独立成功，这个城墙就真的要成为两国的边境墙，届时可能要用混凝土来进行加固。目前的民调结果显示，反对苏格兰独立的呼声较高。
The referendum on whether Scotland should leave the UK is still a year away - but a group of craftsmen have already started the job of dividing England from its northern neighbor.
Four dryliners from Cumbria are helping to rebuild parts of Hadrian's Wall, which was erected by the Romans to keep the 'barbarian' inhabitants of Scotland out of 'civilized' England.
The project is intended as a way of protecting the ancient stone wall - but one of the workers jokes that they may have to reinforce the barrier with concrete if the referendum is successful in splitting up Britain.
Hadrian's Wall was built in the 2nd century AD and manned by Roman soldiers, who wanted to protect their British territory from the Picts who lived in what is now Scotland.
Ever since the Act of Union in 1707, the wall has run across the middle of the United Kingdom - but after next year's referendum, it could become an international border once again.
Every inhabitant of Scotland will be asked to vote on the question, 'Should Scotland be an independent country?' on September 18 next year.
Most polls suggest that the referendum question is likely to be rejected, but if it succeeds it will fundamentally change the landscape of Britain.
The four dryliners who are rebuilding Hadrian's Wall are more interested in contributing to history than arguing about politics, however.
George Allonby, Mark Jennings, Steven Allen and Geoff Capstick are taking original Roman stone from stronger sections of the wall in order to reinforce the weaker sections.
They are shifting 10 tonnes of stone every day as part of the £500,000 project, which was commissioned by the Hadrian's Wall Trust and will continue until the end of next month.
Hadrian's Wall takes its name from the Emperor Hadrian, who ruled over the Romans at the time the fortification was first constructed in 122 AD.
The wall stretches across northern Britain from the River Tyne in the east to the Solway Firth in the west, roughly dividing the territory of the Romans from that of the Picts.
The vast majority of the wall is now in England, suggesting that the border between the two countries has shifted north since ancient times.
It was dotted with fortified towers which would have provided the bases for Roman soldiers defending the territory and inhabitants of their empire.
Although much of Hadrian's Wall is now in a state of relative disrepair, it is still a notable landmark in the region and is popular among hikers walking its 84-mile length.
'This is a really enjoyable job,' Mr Allen said. 'To think you're working with stone somebody put in 2,000 years ago. And leaving something at the end of the day that'll be there in 200 to 300 years - there's not many jobs that are like that.
'It's about picking the right stone to go in the right place. You've got to look for the one that's going to fit. That comes with experience. It's a big jigsaw.'
Bryan Scott, from the Hadrian's Wall Trust, said: 'By repairing the dry stone wall we're protecting the Roman wall underneath.
'The wall was built to separate Romans and barbarians. The wall is still used as a boundary - but now it's between fields rather than Romans and barbarians.'
Mr Scott also joked that it might be time to rebuild the wall entirely if the independence referendum drives England and Scotland apart.
'A local civil engineering firm was asked to calculate the cost of a wall made of concrete,' he said. 'It was £80million at 1974 prices - maybe we should think about it if there is a "yes" vote for Scottish independence next year?'
