One of the most famous Roman landmarks in the world, Hadrian’s Wall stretched for 73 miles (117km) across northern England from Newcastle upon Tyne in the east to Bowness-on-Solway in the west. The incredible structure was built in AD 122 to guard the northern frontier of the Roman Empire, under the orders of emperor Hadrian. The surviving portions of Hadrian’s Wall are now on the UNESCO World Heritage List and considered among the most impressive ancient Roman monuments in the country.

Dominating a vast volcanic outcrop above the River Forth, this foreboding fortress was a key component of the Kingdom of Scotland.

Today, the magnificent structure is one of Scotland’s most popular attractions.

The natural history collection was originally part of the British Museum’s collection in west London and it wasn’t until the 1850s that scientist Richard Owen suggested it should have its own building.

Today, the incredible Romanesque structure is considered a work of art and is one of London’s most recognisable landmarks.

Tangled in pagan history and myth, beautiful Glastonbury Tor has been one of England’s most important spiritual sites for more than 1,000 years.

Just off the western coast of Scotland, St Kilda is the most remote part of the British Isles. Hirta is the largest island of the rugged archipelago and was the first to be settled by humans around 4,000-5,000 years ago. By the 1930s Hirta’s last few residents had departed the inhospitable environment for mainland Scotland. Today it’s better known for its birdlife, although stone settlements remain dotted across the island, serving as an eerie reminder of the past.

Possibly the most famous palace in the world, the Queen’s home was not always a lavish royal residence. Originally built in the 18th century as a townhouse for the Duke of Buckingham, the house was bought by George III in 1761 for his wife, Queen Charlotte. Architect John Nash then transformed it into an impressive palace fit for royalty. Sadly the king died before he could move in so Queen Victoria became the first monarch to live there. Since then, Buckingham Palace has become one of England’s most-visited attractions.

Perched on a cliff overlooking the North Sea, the imposing façade of Whitby Abbey is one of the most celebrated sights in North Yorkshire. The construction of the first Gothic church began around 1225 but, due to lack of funds, it was only finished a few centuries later.

Bad weather, along with bombardment during the Second World War, has eroded much of the abbey’s remains, giving it a hauntingly beautiful and suitably Gothic appearance.
