罗马人从未征服苏格兰（Caledonia）

Giải thích

罗马人称苏格兰为“Caledonia”。他们从未成功永久征服苏格兰，这就是为什么建造Hadrian's Wall来标记北部边界。Britannia是罗马行省不列颠的名称，Londinium是伦敦。

The Romans called Scotland 'Caledonia'. They never managed to permanently conquer it, which is why Hadrian's Wall was built to mark the northern boundary. Britannia was the Roman name for the province of Britain, and Londinium was London.
