I was quite surprised when I found out where these were. A few years ago, before my TMA interests, I’d attended a job interview in the modern office block that overlooks the mounds. I remember assuming at the time that they were just a modern landscaping feature…
Antiquarian descriptions state that the mounds were once all surrounded by ditches and outer banks, but these are no longer visible. What are visible today are the inevitable cycle tracks across the tops of the mounds, which are situated a short walk from the shopping centre. The mounds are fairly evenly spaced, on a N-S line. Only one is undisturbed, three having large depressions indicating where shafts have been sunk, and the two most southerly have been tunnelled from the sides.
All in all, a bit of an anachronism in the modern(!) town, but I’m glad they’ve managed to survive.
