Dorset packs a remarkable amount of history into a small county. You can walk a ruined royal castle in the morning, tour a grand Tudor mansion after lunch, and stand inside an Iron Age hillfort before the light goes.
The county’s story runs from prehistoric earthworks to Henry VIII’s coastal forts and the scars of the Civil War. Below you will find the highlights, what makes each one special, and a few practical notes. Autumn and winter are good times to visit, with fewer visitors and dramatic skies over the stone.
Corfe Castle
Corfe Castle is the one most people picture first, and for good reason. Its broken towers stand on a steep hill in a gap in the Purbeck ridge, visible for miles.
The castle dates back to the years after the Norman Conquest and was once a royal stronghold. It was partly destroyed during the English Civil War, when it was deliberately slighted to stop it being used again. What remains is a dramatic ruin, now cared for by the National Trust.
The village at its foot is worth time in its own right, built from the same grey Purbeck stone. It makes an easy, atmospheric half day, especially on a crisp autumn morning with mist in the valley.
Sherborne’s two castles
Sherborne is unusual, because it has two castles a short walk apart. Together they tell a neat story of English history.
The Old Castle is a ruined 12th century bishop’s palace, now in the care of English Heritage. It too was slighted after the Civil War, and its fractured walls sit in quiet grounds. Across the lake stands Sherborne Castle, the grand house begun by Sir Walter Raleigh at the end of the 16th century. It has been a family home for centuries and sits in wide parkland with a lake.
The newer castle usually opens seasonally, so check ahead before you travel. Seeing the medieval ruin and the later mansion together gives you a real sense of how tastes and power shifted.
Lulworth Castle
Lulworth Castle is not a defensive fortress but an early 17th century mock castle, built as a grand hunting lodge to entertain royalty and aristocracy. It sits in parkland on the Lulworth Estate, near the famous cove.
A serious fire gutted the building in 1929, and it has since been stabilised and partly restored. Today you can explore the shell and climb the tower for views over the estate and out towards the coast. The grounds are family friendly and pair naturally with a walk to Lulworth Cove on the Jurassic Coast.
Henry VIII’s coastal forts
When Henry VIII feared invasion, he built a chain of artillery forts along the south coast. Two of the best sit on the Dorset coast near Weymouth.
Portland Castle is one of the best preserved, an English Heritage site built on the Isle of Portland between 1539 and 1541. Its squat, rounded walls were designed to mount cannon and guard the harbour. It is well worth a visit for a clear picture of Tudor coastal defence.
A short distance away, the ruins of Sandsfoot Castle stand on the cliffs above Weymouth Bay. It was built in the same period as Portland’s partner fort. Coastal erosion has taken part of it, but the remains are free to visit and give fine sea views.
Maiden Castle and prehistoric Dorset
Not every historic site has walls. Maiden Castle, just outside Dorchester, is one of the largest Iron Age hillforts in Europe.
Its huge ramparts ripple across the hilltop, dug by hand more than two thousand years ago. There is no building to tour here. Instead you walk the earthworks themselves, with wide views over the countryside and a strong sense of the people who built them. It is free, open all year, and especially striking in low autumn light.
More history to seek out
Dorset has plenty beyond the headline names, so leave room to explore.
Nothe Fort in Weymouth is a Victorian coastal fort, run by volunteers, with tunnels, guns, and harbour views. Christchurch, now in Dorset, has the ruins of a Norman castle and a fine medieval priory church. Across the county you will also find abbey remains, old market towns, and the great chalk figure of the Cerne Abbas Giant carved into the hillside.
Planning your visit
A little planning goes a long way with historic sites. Opening times vary through the year, and some places close or reduce hours over winter, so check each site before you set out. National Trust and English Heritage members can visit many of these for free, which quickly pays off over a few days.
Basing yourself centrally in Dorset keeps drive times short and lets you fit two sites into a single day. With so much within easy reach, Dorset rewards anyone who likes their history out in the open air. Get in touch today to find out more or to book your holiday cottage in Dorset.
