Our Portchester Castle Highlights
Believe it or not, but even after five years of being together, and three years of traveling, we have only been to a handful of castles in England.
That's despite our love for all things history, architecture, and road trips! Having spent all of 2023 in Asia and then the start of 2024 in Canada, we came back to the UK determined to get some more castles under our belts.
Starting with Portchester Castle, a fascinatingly well-preserved structure with the proud title of being one of the oldest in the entire country!
One of the most intriguing aspects of any castle (in our opinion) is moats and keeps. We are always drawn to them (pardon the pun, drawbridge anyone).
Even though most of the time, moats are long since devoid of any water, they give a cool impression of how severe the security situation may have been.
Some have them, some don't, but Portchester certainly did. That, along with a very impressive keep that despite the giant crack coming down from its side, is still standing tall after nearly 2 centuries.
Portchester Castle certainly has plenty of photo opportunities, be it outside or inside.
Access to the keep is chargeable, but if you don't want to do that, wandering the grounds inside, checking out the castle's famous Norman church, and perusing the outside and coastal walk is free.
Unless, of course, you drive here, in which case the car park will cost you a small sum of £2 for an hour. Not too bad!
You are welcome to make a small donation should you so wish, regardless of buying a ticket to the castle keep.
Portchester Castle is managed by the National Trust, and a particularly nice touch is that you can go inside the main gate and take a look at the inner courtyard for free.
The gate itself is in great condition, and once inside, you can get a really good feel for how impressive this fortification once was.
Typically, castles would have had wooden structures inside, long lost to history, but Portchester did feature a good amount of inner stone buildings consisting of rooms and chambers attached to the keep.
This clearly demonstrates its importance to King and country.
⪢ St Mary's Church
St Mary's Church, which sits in the far right-hand corner of the extensive castle grounds as you walk in, is one of the few remaining functioning Norman Churches.
These precious structures have typically been lost over time to looting, degradation, or war, but St Mary's stands as a beacon of resilience in the face of numerous challenges over its incredible lifespan.
While keeping the Anglo-Saxon love of round arches and tower-like churches (turriform), the Normans, with their superior masonry skills, built sturdier structures.
Their walls were thicker, allowing for wider naves (the main halls where worshippers gathered). Additionally, they employed stronger round arches, often adorned with intricate stone carvings, adding a touch of Norman grandeur to the familiar Anglo-Saxon design.
That is what makes the preservation and endurance of St Mary's just so special!
The History of Portchester Castle
Portchester Castle isn't your typical medieval fortress. Its story stretches back nearly 2,000 years, encompassing Roman defenses, Saxon settlements, and even a stint as a prisoner-of-war camp.
Here's a comprehensive look at the castle's fascinating history:
⪢ Roman Beginnings (3rd Century AD)
Portchester's story starts with the Romans. Facing Saxon raids on the British coast, they constructed a massive stone fort around 300 AD.
This impressive structure, one of the most complete Roman forts in northern Europe, formed the core of what would become Portchester Castle.
Imagine soldiers patrolling the very walls you'll walk!
⪢ Saxon Transformation (5th Century AD)
As Roman power waned in Britain, the fort became a refuge for Saxon settlers in the 5th century.
They adapted the Roman structures, building houses and workshops within the fort's walls. Portchester transitioned from a military base to a bustling Saxon community.
⪢ Medieval Makeover (11th-15th Centuries)
Following the Norman Conquest of 1066, Portchester entered its medieval phase.
A powerful Norman lord, likely William Maudit, built a motte and bailey within the Roman fort, creating the castle's inner ward. This transformed Portchester into a formidable stronghold.
The castle became a favorite haunt of royalty. King John, famous for signing the Magna Carta, used Portchester Castle as a hunting lodge.
Imagine jousting tournaments or hunting feasts within these ancient walls! The 12th century also saw the construction of a unique Norman church within the castle grounds, one of the very few to survive intact.
⪢ Royal Hub and Wars (14th - 16th Centuries)
Portchester's strategic location made it a crucial embarkation point for English forces crossing the Channel.
Notably, King Henry V used the castle to launch his invasion of France in 1415, culminating in the famous victory at Agincourt.
The castle walls must have buzzed with activity as soldiers prepared for this historic campaign. The castle also saw its fair share of conflict.
In 1216, the French even captured Portchester Castle for a brief period, before it was retaken by the English.
⪢ Shifting Purposes (17th-19th Centuries)
By the 17th century, advancements in weaponry rendered Portchester Castle obsolete as a military fortress. It was sold to private ownership and even used as a prison during the 1665 Anglo-Dutch War.
The most fascinating use of the castle came during the Napoleonic Wars (1793-1815). It became a massive prisoner-of-war camp, housing thousands of captured French soldiers.
Interestingly, the prisoners staged theatrical productions within the keep, adding a touch of unexpected culture to the wartime setting.
⪢ Preserved Past (20th Century - Present)
The 20th century saw Portchester Castle come under the care of English Heritage. Today, it stands as a remarkable testament to England's rich history.
Visitors can explore the Roman fort remains, climb the medieval keep, and visit the well-preserved St Mary's Church.
10 Interesting Facts About Portchester Castle
1. Roman Remix: Portchester boasts the best-preserved Roman fort in northern Europe, with its walls standing nearly intact since the 3rd century AD! Imagine walking the very same ground patrolled by Roman soldiers nearly 2,000 years ago.
2. Saxon Sanctuary: After Roman rule crumbled, Portchester transformed into a Saxon settlement in the 5th century. The Roman fort walls became a haven, housing Saxon homes and workshops within their sturdy embrace.
3. Medieval Makeover: The Normans, following their 1066 conquest, revamped Portchester. A powerful Norman lord built a mighty motte and bailey inside the Roman fort, creating the castle's inner ward and solidifying its defensive capabilities.
4. Royal Playground: King John, the Magna Carta king, had a surprising fondness for Portchester Castle. He used it not for military might, but as a personal hunting lodge. Picture jousting tournaments or grand hunting feasts within these historic walls.
5. Hidden Gem: Tucked away within the castle grounds is a unique 12th-century Norman church. One of the very few to survive intact, it offers a glimpse into medieval religious life alongside the castle's more martial history.
6. French Fries or French Toasts? In a brief but dramatic episode in 1216, the French captured Portchester Castle. Luckily for the English, they were swiftly ousted. Perhaps they were just after a hearty English breakfast?
7. Prisoner's Dilemma: By the 17th century, Portchester Castle's military purpose waned. Ironically, it found new use as a prison, first housing Dutch prisoners of war in the 1660s.
8. Global Garrison: During the Napoleonic Wars, Portchester Castle became a massive prisoner-of-war camp. It housed a staggering number of captured French soldiers, some estimates reaching up to 8,000!
9. Theatrical Turn: Those resourceful French prisoners didn't just sit idly. Records show they even staged theatrical productions within the keep during their confinement, adding a touch of unexpected culture to their wartime experience.
10. Friendly Ghost (Maybe): Local legend whispers of a Roman soldier's ghost haunting the castle grounds. While unsubstantiated, it adds a touch of spooky charm to Portchester's rich history.

Our Experience Rating:
Portchester Castle
We are guessing you wouldn't have gotten this far into this post if you weren't a fan of castles, and how synonymous they are with British history.
There are some 4000 castles remaining in the UK, and we have been to a fair few of them in our time. Where does Portchester Castle rank?
Well, it is right up there as one of the oldest built, and we would say it is right up there as one of the most charming too, especially given how close it is to the water.
It is very well preserved, especially given the intense activity that occurred here over the years. The church on the grounds is a delight, too.
Having said all of that, there is not a great deal to do here, and it is a ruin, so with that in mind, if you are looking for activities and stately rooms, this is not the castle for you.
