I didn't put the pin there. I put it on Quay Headm by Milk Thistle. Your mapping puts Mylnes Culvert under Broad Quay, which is incorrect. The culvert below the Centre is a separate entity that terminates below Cascade Steps, close to No.1 Harbourside. Two culverts. Mylnes Culvert goes around St Stephens Street and then follows Marsh Street. Please escalate this issue as you seem unable to make sense of my words.
