The order of importance was the other way round, when the Boston quarter of Skirbeck developed at the head of the Haven, which lies under the present Market Place. At that stage, The Haven was the tidal part of the stream, now represented by the Stone Bridge Drain (), which carried the water from the East and West Fens. The line of the road through Wide Bargate, to A52 and A16, is likely to have developed on its marine silt levees. It led, as it does now, to the relatively high ground at Sibsey (), and thence to Lindsey.
