The ancient city of Bath in the southwest of England has the rare honour of holding dual UNESCO status. The city, in its entirety, was designated a World Heritage Site in 1987, and it was recognised again in 2021 as one of Europe's historic 'Great Spa Towns'.

At the core of the captivating city is its Roman baths, encompassing the temple of the goddess Sulis Minerva and a sprawling bathing complex, which are still fed by mineral-rich hot springs today. For centuries, the springs were thought to have healing powers, leading to Bath's rebirth as a fashionable health resort in the Georgian period. The Neoclassical architecture from this era can be seen throughout the city's elegant centre.

Northern Ireland's first UNESCO World Heritage Site, the Giant's Causeway on County Antrim's Causeway Coast is one of the UK's most historically important natural landmarks. The rock formation comprises 40,000 hexagonal basalt columns hewn by volcanic eruptions and erosion around 60 million years ago during the Palaeogene Period. This remarkable site has been instrumental in our understanding of the Earth's geological history.

Alongside its unusual organic geometries, the Causeway Coast is also a conservation area that's home to an array of plantlife and protected species, including rare snails.  

Canterbury Cathedral in the southeastern county of Kent is a regal patchwork of Gothic and Romanesque architecture. But beneath its imposing exterior are the bones of a small but significant Saxon church, which was built by Saint Augustine, a young monk sent from Rome to England in AD 597 to bring Christianity to the Anglo-Saxons.

The religious edifice, one of the oldest Christian structures in England, has been at the centre of some of the most important events in history, as well as tumultuous upheavals, including the Norman Conquest in 1066 and the murder of Archbishop Thomas Becket in 1170.

There's a reason why the Lake District has captured the imaginations of writers and artists throughout the centuries. The breathtaking mountains, valleys and lakes of this Cumbrian beauty spot are unparalleled. While its peaks and troughs are the result of 500 million years of geological events, human industry, including farming and quarrying, has also shaped its picturesque terrain.

Such is the Lake District's importance that it sparked a movement to protect the country's cultural landscapes and make them accessible to all, leading in part to the creation of the National Trust, Europe's largest conservation charity.

Blenheim Palace in Oxfordshire attracts hundreds of thousands of visitors every year. The storied Baroque mansion is one of the UK's most notable stately homes and the current residence of the 12th Duke of Marlborough. Constructed in the early 1700s for the 1st Duke of Marlborough, it's perhaps better known as the birthplace of Sir Winston Churchill, the British prime minister who led the nation to victory in World War II. 

The estate's elaborate gardens were the work of famous 18th-century landscape architect Capability Brown, while the palace's gilded state rooms are a particular highlight.

The enigmatic Orkney Islands off the northeastern coast of Scotland have an exceptional Neolithic legacy. Around 5,000 years ago, the isle was home to a prehistoric society that produced remarkably sophisticated stone constructions, some of which are still standing today.

Designated a UNESCO World Heritage Site in 1999, the ancient landmark is known as the Heart of Neolithic Orkney and comprises four monuments crafted for domestic and ceremonial purposes. Pictured here is one of the sites, Skara Brae, an astonishingly well-preserved settlement that features stone walls, corridors and furniture. 

Recognised as a site of significant geological heritage, Cuilcagh Lakelands was made a UNESCO Global Geopark in 2001. The awe-inspiring landscape extends from County Fermanagh in Northern Ireland to County Cavan in the Republic of Ireland, making it the world's first transnational geopark. 

The mountainous terrain is punctuated with tranquil lakes, prehistoric rockfaces and limestone fossils that offer a window back in time to the sea creatures who occupied the region millennia ago. In the foothills of Cuilcagh Mountain, the Marble Arch Caves are especially enchanting. Guided tours allow visitors to traverse the labyrinthine passages and underground rivers, beneath a ceiling of ancient stalactites. 

Dubbed the birthplace of the Industrial Revolution, the discoveries made at Shropshire's Ironbridge Gorge in 1709 had a monumental impact across the world. Ironmaster Abraham Darby was the first person to use coke, a fuel produced from heated coal, to smelt iron, instead of charcoal. Darby's innovation vastly increased Britain's iron production and led to the construction of the Iron Bridge, the world's first bridge made from iron.

Today, the village of Ironbridge features historic buildings, museums, monuments and artefacts that tell the fascinating story of this industrial Silicon Valley, which was considered the most technologically advanced place in the world by the end of the 18th century.

The UNESCO Global Geopark of GeoMôn spans the island of Anglesey, located off the northwest coast of Wales. This extraordinary isle is a geological treasure chest with over 100 rock types representing almost every geological chapter in the Earth's history – from ancient volcanic formations shaped by tectonic shifts to remnants of the last Ice Age. Its varied geology has given rise to a dramatic landscape of rugged coastline, soaring cliffs and hidden coves.

Traces of ancient settlements and monuments are scattered across Anglesey, offering a window into its prehistoric past and early industries. A striking example is Parys Mountain, a former Bronze Age copper mine, where red and orange soil create a surreal, otherworldly landscape.

An iconic landmark of the English capital, William the Conqueror ordered the construction of the Tower of London on the north bank of the River Thames in the 1070s after gaining control of the country following the Norman Conquest. The Tower has expanded over the centuries and served many purposes – including a royal palace, an arsenal and a prison, where the likes of conspirator Guy Fawkes, explorer Sir Walter Raleigh and Anne Boleyn, the second wife of Henry VIII, were held.

These days, the famous attraction is home to the yeoman warders, the Tower's historic protectors, a flock of ravens and the British crown jewels, which have been guarded there since the 1660s.

Few UK sites conjure up as much intrigue as Stonehenge, an ancient monument in Wiltshire. It's considered to be the most sophisticated prehistoric stone circle in the world, constructed some 4,500 years ago – around the same time as Egypt's Great Pyramid. 

While the monument's purpose has been shrouded in mystery for centuries, the most widely accepted theory is that it was designed as a temple aligned with the movements of the sun. The complex configuration of stones is said to frame the midsummer sunrise and midwinter sunset, crucial seasonal events for the land's ancient agrarian societies. Burial grounds scattered across the wider site also suggest people may have gathered here to honour their ancestors. 

Founded by wealthy businessman Sir Titus Salt in 1851, Saltaire in West Yorkshire is a remarkably well-preserved industrial village. The site was built to house workers for Salt's textile mill and featured high-quality housing, a school, a park, a hospital and a church, a dramatic departure from the poor living conditions endured by most factory workers at the time.

Saltaire became a blueprint for urban development and went on to transform social welfare across the country. Visitors can explore the village's original Italian Renaissance-inspired buildings, which are now intertwined with its bustling modern community. 

Spanning 95 miles (153km) from Exmouth in Devon to Studland Bay in Dorset, the Jurassic Coast was designated a UNESCO World Heritage Site in 2001 for its geological importance. The stunning stretch is one of the UK's most beautiful and fascinating coastlines. Across its breathtaking cliffs, coves and sea stacks, 185 million years of history are laid bare thanks to rocks and landforms from the Triassic, Jurassic and Cretaceous Periods. 

Described as a geologist's ultimate outdoor laboratory, the fossils preserved within the landscape have provided an invaluable timeline of the Earth's history, from extinction events to evolutionary progress.

The Royal Botanic Gardens at Kew in southwest London was founded in 1759 as a royal estate, before growing into a pioneering centre for conservation and plant science. Its expansive catalogue includes more than 50,000 plant species and 1.2 million fungal specimens and reflects centuries of botanical exploration.

The site's varied terrains include manicured lawns and gardens, rugged woodlands and exquisite Victorian glasshouses. A favourite among visitors, the most famous structure is the iconic Palm House (pictured here), which contains a humid, indoor rainforest filled with rare tropical plants.

Renowned for its rich cultural and architectural heritage, Edinburgh's Old Town and New Town were made UNESCO sites in 1995. The two regions of the Scottish capital encompass 4,500 buildings and tell a story of more than 800 years of urban development.

The enchanting Old Town, with its winding streets, historic stone buildings and regal castle, is a living museum of sorts that offers a snapshot of the city's medieval origins. In stark contrast, the New Town is an 18th- and 19th-century expansion of elegant Georgian townhouses, crescents and squares – one of the finest examples of urban planning in the Age of Enlightenment.

These days, it's a popular walking route; however, Hadrian's Wall was the defensive barrier of the northwest frontier of the Roman Empire for almost 300 years. The extraordinary fortification stretches 73 miles (117km) between the Cumbrian and Northumberland coastlines. Commissioned by Emperor Hadrian, construction is thought to have begun in AD 122 and taken at least six years to complete. 

Along the route, you can discover the remnants of the forts, watchtowers and settlements that once guarded the border, which also functioned as a vital trading point between Europe and North Africa.

A pioneering feat of Victorian engineering, the Forth Bridge connects South Queensferry on the banks of Edinburgh with North Queensferry in Fife. Its innovative design comprises three double cantilevers that support two 1,700-foot (518m) spans – at the time of its opening in 1890, they were the longest bridge spans in the world. The bridge's completion signified the first continuous East Coast railway route from London to Aberdeen. 

The monumental structure is affectionately known by locals as 'Our Grand Old Lady', and in 2016, it was crowned Scotland's greatest manmade wonder following a public vote.

Jodrell Bank Observatory in the northwest county of Cheshire is best known as the home of the Lovell Telescope – the UK's largest radio telescope. The trailblazing centre has played a leading role in space research since the 1950s, from tracking Soviet and American space missions during the Space Race to receiving the first images of the surface of the Moon in 1966.

The complex is still at the forefront of modern astrophysics today. Alongside its cutting-edge research, the observatory is open to the public and offers various educational pavilions that house interactive exhibits, planetarium shows and space artefacts.

The Castles and Town Walls of King Edward in Gwynedd, North Wales, are a collection of four 13th-century fortifications built by King Edward I during his conquest of Wales. They include the castles of Beaumaris, Harlech, Caernarfon and Conwy – the latter two include fortified towns constructed within the castle walls. Designed by James of St George, the King's chief architect, they're some of the finest examples of medieval military architecture in Europe.

Miraculously, the fortress ruins we see today still resemble the original plans from centuries ago, with towers, dungeons, gates and other defensive features on show. 

Prized for both its natural and cultural heritage, the islands of St Kilda in Scotland's Outer Hebrides are the UK's only mixed UNESCO World Heritage Site. The uninhabited archipelago, known as the islands at the end of the world, provides a habitat for almost a million seabirds, which include the UK's largest Atlantic puffin colony.

A small community occupied St Kilda for thousands of years, though life on the remote outpost was hard. In 1930, the remaining 36 islanders voted to evacuate and relocate to the mainland in search of more favourable living conditions. Now all that remains are the abandoned structures they left behind.
