Introduction
From the slopes of Mount Caburn that September morning, I could just see Lewes Castle rising through the mist — the twin mottes catching the first light over the town. It’s one of the earliest Norman castles in England, begun around 1069 by William de Warenne, one of William the Conqueror’s most trusted knights.

It’s hard to believe this view has changed so little in nearly a thousand years.

The Norman Conquest Comes to Lewes
Lewes Castle was the second Norman stronghold in Sussex, built soon after Hastings Castle to secure the route inland and protect the road to London. Its position on the ridge above the River Ouse made it both a defensive lookout and a statement of dominance over the surrounding Saxon population.
The earliest castle would have been a timber motte-and-bailey, replaced in stone through the 11th and 12th centuries. The outer towers seen today were added in the 13th century under the Angevin kings — part of the continual strengthening of Norman fortifications across southern England.
Strategic Importance
Lewes controlled the key route between the south coast and the old capital at Winchester. From here, Norman lords could oversee trade and movement along the Ouse Valley and the approaches to the Downs. It formed one link in a chain of coastal strongholds, including Hastings, Pevensey, and Arundel, that secured William’s new kingdom against rebellion and invasion alike.
Visiting Today
You can still climb the steep steps up to the keep and take in the same commanding view that once overlooked the Norman road north. Inside the walls, the museum tells the story of Lewes through Saxon, Norman, and medieval times.
It’s not just a monument — it’s a reminder of how one battle reshaped an entire country.
