Fascinating Hertfordshire Facts
The World’s First Garden City
In 1903, Hertfordshire’s town of Letchworth became the world’s first “garden city.” This innovative urban plan aimed to combine the benefits of the countryside and the city for healthier living, influencing town planning around the world.
Britain’s First Recorded Martyr
St Albans, a historic city in Hertfordshire, is named after Saint Alban, Britain’s first recorded Christian martyr. According to legend, he saved a priest by swapping places, was executed by the Romans, and is now the patron saint of Hertfordshire. The city’s impressive cathedral is one of the most ancient, and significant in England.
Harry Potter and Hollywood Magic
Hertfordshire is home to Warner Bros. Studios in Leavesden, where much of the Harry Potter film series was shot. The county is a hub for British cinema history, with classic films and TV shows, like parts of the original Star Wars trilogy and EastEnders, also filmed in Borehamwood and Elstree Studios.
