It was once a kingdom during the early medieval period, playing a significant role in the development of Christianity in England, particularly through the influence of figures like Bede. Today, Northumbria encompasses several counties, including Northumberland and parts of County Durham. The area is famous for its picturesque coastlines, the Northumberland National Park, and historical sites such as Hadrian's Wall, which marks the northern boundary of the Roman Empire in Britain.
