Slyne preserves a very early Anglo-Saxon name for a slope. In the Domesday Book it was referred to as ‘Sline’, so it is likely to have been said in roughly the same way for well over a thousand years. It comes from ‘slinu’, the Old English for slope.
Although not particularly steep, Slyne is on a ridge and the old Slyne Manor House is on a slope. Slyne is on the A6. At this point the road largely follows the course of the probable Roman Road from Lancaster to Watercrook near Kendal.
This old photo of Slyne shows the gentle slope on which it sits.
