Somersetshire

Mendips above the Levels, Quantocks beyond, Exmoor rising towards the western sea.

Somerset contains one of England’s strongest sequences of contrasting landscapes. The limestone Mendips rise across the north above the immense flat country of the Somerset Levels; beyond the Levels stand the Quantocks; further west the county climbs again into the high moorland of Exmoor before falling dramatically to the Bristol Channel.

Bath occupies the Avon valley in the north-east; Wells sits beneath the Mendips; Glastonbury Tor rises conspicuously from the lowlands; and Taunton belongs to the gentler country beyond the Quantocks. Rivers, hills and wetland repeatedly divide and reconnect the county, creating a landscape much more varied than its popular associations with cider and orchards suggest.

Mendips and Levels

The Mendips form a long limestone ridge of caves, dry valleys and gorges. Immediately to their south lies an almost opposite landscape: the Somerset Levels and Moors.

Here the land falls close to sea level, with rivers, rhynes, drainage channels, peat and former islands creating an intensely water-shaped countryside. The contrast between limestone height and reclaimed wetland is one of Somerset’s defining geographical relationships.

Parrett and the wetland basin

The Parrett and its tributaries drain a large part of central Somerset towards Bridgwater Bay. The Brue and Axe organise other parts of the Levels.

For centuries the challenge has been not simply crossing this landscape but managing water within it. Drainage altered the Levels profoundly without removing their fundamental wetland character.

Quantocks to Exmoor

West of the Levels, the Quantock Hills rise as a wooded and heath-covered ridge before the land opens towards Exmoor.

Exmoor gives western Somerset a wholly different scale, with high moor, deeply cut valleys and a dramatic coast. Dunkery Beacon provides the county’s highest ground.

County questions

Questions about Somerset

Is Bristol a separate geographic county?

No. Bristol’s historic county-corporate status did not make it a separate geographic county. The old course of the Avon divides the historic city between Gloucestershire to the north and Somerset to the south.

Why are the Somerset Levels so flat?

They are low-lying wetland, former estuarine and peat country shaped by rivers, sediment, drainage and reclamation. Slight rises consequently stand out with unusual prominence.
