Hertfordshire (often called Herts for short) is a county in the East of England. It's one of the "home counties," which means it's close to London. Hertfordshire shares its borders with Bedfordshire to the north-west, Cambridgeshire to the north-east, Essex to the east, Greater London to the south, and Buckinghamshire to the west.
The biggest town in Hertfordshire is Watford, and the county town (where the main local government offices are) is Hertford. The county covers about 1,643 square kilometers (634 square miles). In 2021, about 1.2 million people lived here. After Watford, other large towns include Hemel Hempstead, Stevenage, and the city of St Albans.
Hertfordshire has higher land in the north and west, especially in the Chilterns area near Tring. The county has many farms, and a lot of its open land is part of the Metropolitan Green Belt. This is a special area that helps stop cities from growing too much.
Hertfordshire is known for its "garden cities" and "new towns." Letchworth was the world's first garden city, designed to combine city life with nature. Stevenage was one of the first towns to be planned and built after World War II. Today, most jobs in Hertfordshire are in the services sector, like shops, offices, and healthcare.

Exploring Hertfordshire's Past
Hertfordshire has a long and interesting history, with many old buildings and landmarks. You can find everything from ancient Roman sites to famous film studios. Many medieval and Tudor buildings are still standing, especially in St Albans. This city also has parts of the Roman town of Verulamium.
How Hertfordshire Got Its Name
The name "Hertfordshire" comes from the town of Hertford. In 913, a fortress was built there by Edward the Elder. "Hertford" comes from an old Anglo-Saxon phrase, heort ford, which means "deer crossing." The name Hertfordshire first appeared in a history book called the Anglo-Saxon Chronicle in 1011. That's why you often see deer on the county's emblems!
Many towns in Hertfordshire have names that date back to the Anglo-Saxon period. Words like "ford," "ton," "den," and "stead" are common in these old names. For example, Hertford, Royston, Harpenden, and Wheathampstead.
Early Human Life in Hertfordshire
People have lived in Hertfordshire for a very long time, since the Mesolithic period (Middle Stone Age). Farming started here during the Neolithic period (New Stone Age), and permanent homes appeared in the Bronze Age. Later, different tribes settled in the area during the Iron Age.
Roman Times and Saint Alban
When the Romans conquered Britain in AD 43, the local Catuvellauni tribe quickly became part of Roman life. This led to the growth of new towns, like Verulamium (now St Albans). Around 293 AD, the first recorded Christian martyr in Britain, Saint Alban, is believed to have died here. He was a Roman soldier who bravely took the place of a Christian priest. He was beheaded on Holywell Hill.
Saint Alban's story is important to Hertfordshire. His special cross (a yellow cross on a blue background) is shown on the county flag and coat of arms. The yellow background behind the stag (or "Hart") represents the county. Saint Alban is the patron saint of Hertfordshire.
Anglo-Saxon and Viking Times
After the Roman soldiers left in the early 5th century, the area was invaded by the Anglo-Saxons. By the 6th century, most of what is now Hertfordshire was part of the East Saxon kingdom. This kingdom didn't last long, and by the 9th century, Hertfordshire was controlled by the Mercians. It finally became an English shire (county) in the 10th century.
During the Viking invasions, Hertfordshire was often on the front lines. King Edward the Elder built a fort in Hertford to stop Viking attacks. His father, King Alfred the Great, even set the River Lea as a border between his kingdom and the Viking-controlled lands. Even though there were Viking raids, many Anglo-Saxon traditions and names stayed in the area.
Norman Conquest and Later Years
In 1066, after the Battle of Hastings, William the Conqueror received the surrender of English lords and clergy at Berkhamsted. This led to him becoming the new King of England. The Normans built new castles in Hertfordshire, like at Bishop's Stortford.
Later, during the Wars of the Roses, St Albans was the site of two big battles. In Tudor times, Hatfield House was a favorite place for Queen Elizabeth I. King James I used the area for hunting and helped build the New River, which brought drinking water to London.
As London grew, Hertfordshire became a popular place for rich and important people to live. This helped the local economy. The biggest boost came during the Industrial Revolution, when the population grew a lot. In 1903, Letchworth became the world's first "garden city." Later, Stevenage was developed as a "New Town" after World War II.
Hertfordshire in Modern Times
Hertfordshire has played a part in more recent history too. The first German airship (zeppelin) shot down over Britain during World War I happened in Cuffley.
From the 1920s to the 1980s, Borehamwood was home to major British film studios, including MGM-British Studios. Many famous movies were made here, like the first three Star Wars films! American director Stanley Kubrick also lived and filmed in the area. Today, TV shows like EastEnders are filmed at Elstree.
Warner Bros. Studios, Leavesden is another important film location in Hertfordshire. The Harry Potter movies were filmed here, and you can now visit the popular Making of Harry Potter studio tour.
Geography and Landscape
Hertfordshire is in the south-eastern part of England, just north of London. It's part of the East of England region. To the east is Essex, to the west is Buckinghamshire, and to the north are Bedfordshire and Cambridgeshire. Many people who live in Hertfordshire travel to Central London for work.
The county's borders were mostly set in 1844. In 1965, some areas near London, like Potters Bar, became part of Hertfordshire. The highest point in the county is about 244 meters (800 feet) above sea level, near Tring.
Hertfordshire doesn't have huge cities like Luton or Milton Keynes. However, its total population is larger than those of Bedfordshire and Buckinghamshire. The River Lea flows through towns like Harpenden, Welwyn Garden City, and Hertford. The western part of the county is hillier, with the Chiltern Hills near Tring and Berkhamsted. This area is known for its beautiful natural scenery.
Many of Hertfordshire's main towns are in the central, northern, and southern areas. These include Watford, Hemel Hempstead, St Albans, Stevenage, and Welwyn Garden City. Some are historic, like St Albans with its Roman ruins and Norman cathedral. Others, like Stevenage, are "new towns" planned after World War II.
The eastern parts of Hertfordshire are mostly rural, with farms, villages, and smaller towns. These include Royston, Buntingford, and Bishop's Stortford. The landscape here is less hilly but has rivers like the River Stort.
Hertfordshire's Natural Environment
Much of Hertfordshire has beautiful and varied countryside. You can find beech woods in the Chiltern Hills and ancient hornbeam forests. There are also wide open chalklands near Royston and Tring.
A lot of the county's land is used for farming. Some areas also have quarries for sand and gravel. In the past, clay was used for making bricks. The chalk rock under much of the county holds water, which feeds streams and provides water for many homes.
The New River, built in 1613, still supplies fresh water to London from Ware. Hertfordshire's rivers, though small, helped early industries like paper making.
Hertfordshire is home to many different plants and animals. The Pasqueflower, a purple star-shaped flower, is considered one of the county's special flowers.
