Edinburgh Castle, Scotland

Occupied since the Iron Age, Edinburgh Castle is one of the oldest castles in western Europe. Now the epicentre of Scotland’s capital city, visitors can climb the heights of Castle Rock to explore the castle’s tower and tapestries.

Located on the Royal Mile, the castle’s street is also the site of the annual drama and comedy extravaganza, the Edinburgh Festival Fringe as well as the Royal Edinburgh Military Tattoo.

Angus is our local expert on his tour of The Royal Mile – From Huts to High Rise. He’ll paint a vivid picture of how this central Edinburgh street developed from timbered medieval buildings to the bustling street of today.

Dover Castle, Southeast England

Sat atop the iconic White Cliffs of Dover, this castle has a fascinating past. Built shortly after the Battle of Hastings in 1066, Dover Castle is also the site of a Roman lighthouse and medieval tunnels.

The castle’s network of tunnels is three miles long and has been in use since the Napoleonic Wars! Housing over 2,000 soldiers in World War II, the tunnels played a key part in Operation Dynamo during the Battle of Dunkirk. The tunnels were also selected as one of 12 Regional Seats of Government, to be occupied in the event of nuclear war in the 1960s.

Visitors can take in epic views of the cliffs and see across the channel to France from its rooftops. Find out why Kent is the gateway to England in your visit to this breathtaking historical monument.

York Castle, Northeast England

Why not head to the UK’s Viking capital and explore the city’s heritage from the top of this fortress? York Castle was built in 1068 by William the Conqueror, the first Norman king of England; it was built as a stronghold in his military campaign the Harrying of the North, and still stands today.

The famous Clifford’s Tower at York Castle has occupied many roles in its 400-year history, having been a royal mint, a medieval stronghold, and a Civil War garrison. Located on the south side of the River Foss, it offers unparalleled views of York’s skyline from medieval buildings to the Minster.

Best Castles

Cardiff Castle, Wales

Our penultimate Castle has over 2,000 years of history and is located in the heart of Cardiff’s city centre. Born out of a series of forts constructed by the Romans in the 1st century AD, the Castle was updated in the 11th century by the Normans who installed the Keep.

This 12-sided keep towers over the landscape and greets visitors when they enter the grounds. There are roughly 50 steep stone steps leading up to the Keep, but the view alone is worth the effort!

Once inside, take in the lavish Victorian splendour and visit the eerie Black Tower to hear the history of the forgotten Welsh medieval hero Llywelyn Bren.

Warwick Castle, the Midlands, England

That William the Conqueror was certainly a busy chap! Warwick Castle was also built under his instruction in 1068. It was constructed on the bend of the meandering River Avon. Not only is this castle a great day out for families, but you can also sleep over in the summer.

Aside from Warwick Castle’s interesting architectural past, the most powerful trebuchet – a medieval launching weapon – also lives there. In 2006, this record-breaking device launched a 29lb missile at 160mph! Luckily, it’s no longer in use.

And if that doesn’t sate your thirst for turrets and trebuchets, you can visit Kenilworth Castle and Elizabethan Gardens, which is a 17-minute drive north of Warwick Castle.

          The best castle to visit in the UK is set on top of a picturesque grassy hill.
