The imposing escarpment known as Brandshill lies to the north-east of the village and was formerly known as Brent's or British Hill. One theory suggests it was once the site of an Ancient British (preRoman) camp, and though the fortifications which once crowned its summit have long been levelled, there are still vestiges enough on its sides to show that this was a place of obstinate defence.

It is thought there were originally 15 earthen banks along the steep escarpment, each about 1/2 a mile long, which had to be successively breached before an enemy could attack the citadel. That it was perhaps once a place of importance is further emphasised by the number of coins that have been found in the area, along with the discovery of a Bronze Age sword. On the arrival of the Romans it is generally thought they may have adapted the fortifications to meet their own requirements.
