Tattenhall is situated in south west Cheshire, twelve kilometers south east of the city of Chester.
The landscape of the Parish is characterised by the Cheshire Plain, a gently rolling pastoral landscape separating the Sandstone Ridge from the Clwydian range of hills in North Wales.
The Parish lies on the watershed separating two major river systems – the Dee and the Mersey. Of the three water courses which flow through the Parish, the Mill Brook and the Keys Brook flow into the River Dee and in the north of the Parish, the River Gowy flows into the Mersey near Ellesmere Port.
Most of the solid rock underlying this part of Cheshire is classified by geologists as belonging to the Permo-Triassic system, between 225-180 million years old. In the more recent Pleistocene period (between 2 million and 10,000 years ago) most of Cheshire including the Parish of Tattenhall, was covered by a succession of ice advances.
This resulted in the deposition of glacial tills made up of clays, silts, sands and gravels which typify the Cheshire Plain. Much of the glacial drift of this part of the County is boulder clay which has resulted in heavy soils and subsoils. Over recent times, land drainage work has produced typical lush pasturelands which are highly suitable for intensive dairy production – a feature which still characterizes the Parish.
