A large round and roughly carved stone ball has been discovered by a group of archaeologists working on a "dig" at Hay Castle, in the county of Powys Wales.
The Ball, about a foot wide and four and a half stone in weight, was found around fifteen inches deep at the East of the site. It is thought the boulder would have been suitable ammunition for the medieval catapult commonly known as a Trebuchet, And such balls were used in siege warfare throughout Britain, from the year 1217 AD There have been a number of occasions when a siege was conducted at Hay and possibly the stone could easily have been used in The Baron's War 1263 - 1266
The Trebuchet was a favoured weapon of Edward l 1238 - 1307 and employed at the siege of Sterling in Scotland.
