About
Donnington Castle is a striking and historically important medieval castle ruin on a hilltop just north of Newbury in Berkshire, managed by English Heritage and freely accessible to the public. The site is remarkable for the spectacular survival of its 14th-century twin-towered gatehouse, one of the finest and most complete castle gatehouses in England, which stands largely intact to near its original height despite the deliberate demolition of the rest of the castle following a famous and prolonged siege during the English Civil War.
The castle was built in the late 14th century, probably around 1386, when Richard Abberbury the Elder received a royal licence to crenellate his manor house at Donnington. The original castle would have been a quadrangular enclosure with towers at the corners and a gatehouse providing the principal access. The twin-towered gatehouse that survives today was the most architecturally impressive element of this original design, and its survival — while the rest of the castle was demolished — is a piece of remarkable historical fortune.
Donnington Castle is most celebrated, however, for its role in the English Civil War. The castle was held for King Charles I by the loyal Royalist governor Colonel John Boys from 1644 until the end of the first Civil War in 1646 — a siege of exceptional duration that became one of the most famous episodes of the war. Parliamentary forces besieged the castle repeatedly, and despite suffering three Parliamentary sieges and the almost total destruction of the castle buildings by artillery bombardment, Colonel Boys refused to surrender. The garrison endured extraordinary privations and continued to hold out even when the rest of the castle was in ruins around them. Charles I himself visited the castle in 1644 and 1645, and the castle was used as a base for Royalist operations in the Thames Valley. Boys finally surrendered only in April 1646, after the Royalist cause had effectively collapsed following the defeat at Naseby, making the Donnington garrison one of the last Royalist strongholds to yield.
The twin-towered gatehouse survived the Civil War largely intact, apparently because it was used by the Parliamentary garrison following the surrender, and it was subsequently preserved rather than demolished. Today it stands as a monument to both medieval architectural ambition and Civil War endurance, with views across the Berkshire countryside from the hilltop site that explain clearly why the castle was so strategically significant and so stubbornly defended.

- Combine with a visit to Newbury's West Berkshire Museum for context on the Civil War campaigns in the area.
- The hilltop views across the Kennet Valley and North Wessex Downs are excellent — bring binoculars.
- The site is freely accessible at all times and suits spontaneous visits — no need to plan opening times.
- Park in the small car park at the base of the hill and follow the path up — a short but moderate climb.
- Bring the English Heritage site guide or download information in advance as there is no on-site visitor centre.
- Dogs are welcome on leads at this open-access site.
Highlights
The Twin-Towered Gatehouse — A Medieval Masterpiece
The twin-towered gatehouse of Donnington Castle is one of the most impressive surviving medieval gatehouses in England, a tall, elegant structure with two round towers flanking the entrance archway that rises to near its original height despite the destruction visited on the rest of the castle during the Civil War.
The quality of the stonework, the proportions of the towers, and the overall architectural confidence of the design make it clear that this was a building of considerable ambition and expense when it was constructed around 1386. The gatehouse served both a practical function — as the principal defensible entrance to the castle — and a symbolic one, announcing the wealth and status of its builder to all who approached along the road from Newbury below.
Its survival when everything around it was demolished is a remarkable historical accident.
The Great Civil War Siege — Colonel Boys Holds Fast
The most famous episode in Donnington Castle's history is the extraordinary siege of 1644-1646, during which the Royalist garrison under Colonel John Boys resisted three Parliamentary assaults and endured continuous hardship to hold the castle for King Charles I. The first siege in 1644 saw the castle heavily bombarded and much of the fabric destroyed, but Boys refused to surrender even as the buildings around him were reduced to rubble.
The Second Battle of Newbury (October 1644) was fought in part to relieve the castle, and Charles himself visited twice.
Boys finally surrendered in April 1646, one of the last Royalist garrisons to yield after the King's effective defeat. This act of loyalty and endurance made Donnington Castle famous throughout England and Boys was honoured as a hero by the Royalist cause.
Civil War Earthworks — The Siege in the Landscape
Around the base of the castle hill, the earthwork remains of the Civil War siege works can be traced in the landscape — banks, ditches, and gun platforms constructed by the Parliamentary besieging forces during their attacks on the castle. These earthworks, which complement the star-shaped earthwork bastions that Boys added to the outer defences of the castle during the siege, are among the best-preserved Civil War siege earthworks in England and add greatly to the historical depth of a visit to Donnington.
Walking around the base of the hill and identifying the earthwork features allows visitors to reconstruct the tactical situation of the siege and to appreciate the skill and determination that enabled the small Royalist garrison to hold out for so long against a much larger parliamentary force.
Views Across the Berkshire Countryside
Donnington Castle stands on a prominent hilltop that commands wide views across the North Wessex Downs, the Kennet Valley, and the surrounding Berkshire countryside. To the south, the town of Newbury is clearly visible in the valley below, and on clear days the chalk downs of the North Wessex AONB stretch away to the horizon.
The strategic value of this position — commanding the approaches to Newbury and the crossing of the River Kennet — is immediately apparent, and the views explain clearly why this hilltop was chosen for castle-building in the 14th century and why it was so stubbornly fought over in the 1640s.
The combination of impressive medieval gatehouse and panoramic natural views makes the hilltop one of the most rewarding open-air heritage experiences in Berkshire.
Collections
Donnington Castle is an open-air heritage site centred on the surviving 14th-century twin-towered gatehouse and the Civil War earthworks around the castle hill. English Heritage provides interpretation panels explaining the medieval origins of the castle, the Civil War siege of 1644-1646, and the significance of the surviving earthworks.
No collections are held on site; Civil War material relating to the Newbury campaigns is held at the West Berkshire Museum.
