Walk along Mill Lane - so called because it was the road leading from Old Swan to the ancient Wavertree Mill off Woolton Road - past the children's playground. A few yards inside the railed enclosure can be seen a sandstone block, protruding from the grassy surface, inscribed with a crown and the letter 'S'.

This 'Salisbury stone' is a reminder of the old Wavertree Lake which existed on this site until 1929, and of a dispute between the Local Board and the Lord of the Manor as long ago as 1861. The Lake was a valued local asset; the existence of a water supply - springing from the original well - was probably the reason why a village developed here, the name 'Wavertree' having been translated by one scholar as "the place by the common pond". During the nineteenth century, however, it became very dirty and weed-infested, and the Local Board of Health decided to clean it up and plant trees round the edge. This provoked a reaction from the Marquess of Salisbury - Lord of the Manor of Wavertree - who ordered 'mere stones' (boundary markers) to be placed round the edge to show that it was his property rather than common land. Eventually the dispute was resolved - the Marquess agreeing to allow the Board to continue with its scheme - but one of the stones remains to this day.
