Bayston Hill stands on an outcropping spur, of a Pre-Cambrian limestone and sandstone sedimentary rock extension of the Longmyndian range, intruding into the Shropshire plain, with major appearances at Longden, Lyth Hill, Bayston Hill, and Sharpstone Hill.
North of the River Severn it does not outcrop again until it appears east of Shrewsbury as Haughmond Hill.
The sediments were laid down under a vast warm ocean, surrounded by many volcanoes that were ground down by later Ice Age glaciers, which provided the fertile soil that contributed to Bayston Hill becoming a successful farming community throughout medieval times.
There are still several active geological fault lines underlying the area; on 2 April 1990 Bayston Hill experienced an earthquake, measuring 5.4 on the Richter Scale, that was centred on Bishop's Castle.

The village lies just three miles south of Shrewsbury, and is separated from the county town by the main A5 Trunk road.
It has good road transport links, with easy access to both the A49 and A5.
To the south lies the pre-Cambrian Lyth Hill, with Sharpstone Hill standing to the east, the latter now mostly a major sandstone quarry with little of the hill itself now remaining after several hundred years of constant quarrying activities.
