England's northernmost county Northumberland was once part of the Roman Empire and the scene of many wars between England and Scotland. The aftermath of this colourful history means Northumberland has the most castles of all the English counties, including Alnwick, Bamburgh, Dunstanburgh, Newcastle and Warkworth castles.
A primarily rural area, Northumberland's estimated 314, 000 population distribution means it has the lowest population density in England at only 62 persons per square kilometre. The varied landscape of Northumberland is a huge visitor attraction. The county boasts dramatic views and sandy beaches along its coast with a possibility of catching a glimpse of grey seals in the winter, which breed on the Farne Islands off the Northumberland coast. The Northumberland National Park and Kielder Water and Forest Park are perfect for outdoor enthusiasts. Northumberland is also home to the majority of England's iconic Hadrian's Wall, a UNESCO World Heritage Site with breathtaking landscape views largely unaltered since the Roman times.
