The area of the Castle Keep was important long before the Keep was built, a dugout canoe funeral was discovered when the post office building was being constructed and a church was in the area possibly on the Keep area. When the roads and pavements were worked on in the 1970s over 600 burials were discovered in the vicinity of the Keep, it's been assumed that there's many more as a lot of the area is built on and inaccessible. There was a collapsed drain heading towards the High Level Bridge a few years back and workers discovered a mother and child burial. There's still more to be discovered in the city and beyond.
