Visit Alnwick Castle in Northumberland. Explore its medieval history, grand interiors, gardens, and its famous role as a Harry Potter filming location.

A Legendary Castle of Power and Prestige

Towering over the River Aln in the heart of Northumberland, Alnwick Castle is one of England’s most spectacular and best-preserved medieval fortresses. For over 700 years, it has been the home of the Percy family, Dukes of Northumberland, and remains a symbol of northern strength, elegance, and endurance.

Today, visitors can explore grand medieval halls, lavish staterooms, and lush gardens — while recognising the castle’s cinematic fame from Harry Potter, Downton Abbey, and other screen classics.

The History of Alnwick Castle

Alnwick Castle was founded in 1096 by Yves de Vescy, one of William the Conqueror’s Norman barons. Strategically located near the Scottish border, it became a crucial stronghold during centuries of Anglo-Scottish conflict.

In 1309, the castle was purchased by Henry Percy, whose descendants — the powerful Percy family — transformed it into both a fortress and a noble residence. Over time, they rebuilt the interiors into one of the most refined stately homes in England.

Moreover, Alnwick has hosted kings and queens, from Edward IV to Elizabeth II, and survived wars, rebellions, and political intrigue — earning its reputation as the “Windsor of the North.”

Exploring Alnwick Castle
1. The Outer Bailey and Courtyard

Entering through the Barbican, visitors find themselves in the Outer Bailey, surrounded by soaring towers and battlements. The courtyard often hosts medieval re-enactments, archery lessons, and live falconry displays.

2. The State Rooms

Inside, the State Rooms reveal a world of splendour — gilded ceilings, Italian art, and fine furniture collected over centuries. These opulent interiors reflect the Percy family’s wealth and artistic taste.

3. The Film Locations

Fans of Harry Potter will instantly recognise the castle’s courtyards and lawns as Hogwarts School of Witchcraft and Wizardry. Many scenes from The Philosopher’s Stone and The Chamber of Secrets were filmed here. Visitors can even join broomstick-flying lessons in the same spots where Harry learned to soar!

The Gardens and Grounds

Next to the castle lies the Alnwick Garden, a masterpiece of modern landscaping. Created by The Duchess of Northumberland, it features the Grand Cascade, Rose Garden, and the world-famous Poison Garden, home to deadly plants from around the globe.

The contrast between medieval architecture and contemporary design makes Alnwick one of the UK’s most dynamic heritage destinations.

Architecture and Restoration

Alnwick Castle’s architecture blends medieval fortification with Gothic Revival splendour. In the 18th and 19th centuries, architects Robert Adam and Anthony Salvin transformed the fortress into a palatial residence, adding turrets, tracery, and grand interiors without losing its defensive character.

Today, the castle remains the second-largest inhabited castle in England, after Windsor. It continues to balance its role as a family home, museum, and cultural attraction.
