Northumberland is the most northern county in England, with borders reaching from Tyneside to the Cheviot Hills.  Northumberland was once part of the Anglo-Saxon kingdom of Northumbria.  Throughout history, the region has changed hands between the Scots, Danes and Normans.  The Normans laid out the boundaries of the Northumberland that exists today.  Northumberland’s position in the northernmost part of England made it particularly vulnerable to attacks from the Scots.  The English and Scottish fought numerous battles in Northumberland until 1603, when the monarchies combined and the countries stopped fighting.  Northumberland’s landscape is still scattered with castles and fortifications, originally built to protect the area from invasion.  Northumberland’s most famous feature is Hadrian’s Wall.  The 730-mile long wall was built by the Romans between 122 and 130 AD.  It is now a heritage site and important part of the county’s history.
