Caus Castle

Caus Castle is a ruined medieval fortress on the eastern slopes of Long Mountain in Shropshire, near Vennington and within the civil parish of Westbury. Built inside an Iron Age hillfort, it watched over the road between Shrewsbury and Montgomery, close to the border between England and Wales. Today it is a quiet, grassy hilltop of earthworks and low remains, with wide views over the border country.

What is Caus Castle?

The site layers three eras of history on one hill. The outer ramparts probably belong to an Iron Age hillfort, a defended settlement from long before the Normans. Inside it, a motte-and-bailey castle was raised in the Norman period, and beside it a small medieval town grew up. Few places in the Marches show so clearly how a prehistoric stronghold was reused by later rulers.

Who built it and why was it here?

The land passed to the Corbet family after the Norman Conquest; the Corbets were granted manors here in 1069. The family name is linked to the Pays de Caux in Normandy, which is where the castle's name is thought to come from. The hill gave a commanding view of the route from Shrewsbury towards Montgomery, which made it a natural place to control movement across a frontier region where English and Welsh interests often clashed.

Henry II had the castle garrisoned in 1165. In 1198 Roger Corbet rebuilt the tower, keep and curtain wall in stone. In 1263 a royal grant of 50 marks helped pay for D-shaped towers along the curtain wall, a sign that the castle was still considered worth strengthening in the 13th century.

The lost town of Caus

In the late 12th century a borough developed in the outer bailey. It had a church dedicated to St Margaret, while St Nicholas served the castle itself. Market rights were in place by about 1200, so for a time Caus was a real trading settlement, not just a garrison. The town later declined and was deserted, and its streets are now only faint humps and hollows in the grass.

Decline and ruin

When Beatrice Corbet died in 1347, Caus passed to the Earl of Stafford. By 1521 the castle was described as being in great ruin and decay. It was destroyed during the English Civil War and has been a ruin ever since.

What can you see today?

Expect earthworks rather than standing towers: ditches, banks, the raised motte and the outlines of the old enclosure. The value of a visit is in reading the landscape and imagining the fort, castle and market town that once crowded the hillside. Sturdy footwear is a good idea, as the ground is uneven and can be wet.
