The Antonine Wall isn't as well-known as its English equivalent, Hadrian's Wall, but it wasn't any less important. The strip of land bounded by the two walls is known today as the Borders. It's true that this wall, built by the Roman Emperor Antonius Pious between the years 142 and 143 AD has deteriorated a lot more than Hadrian's Wall. It was the first artificial barrier built by the Romans to protect against attacks from local tribes, like the Picts and the Scots. The wall connects Scotland's two largest rivers, the Forth and Clyde. In the village of Twechar, on Bar Hill, there was once a small fort, though nothing remains today.
