Northumberland national park, England- National Parks were designated in order to protect beautiful areas for the nation. Northumberland National Park is situated to the west of the county of Northumberland, sandwiched between Scotland to the North, the North Sea to the east, Hadrian’s Wall to the South and Cumbria to the West, there are around 405 square miles of superb wilderness within the National Park to explore.The most northerly of the National Parks in England, Northumberland National Park is also the least visited and the least populated, although that is due more to its location than to any lack of interesting reasons for visiting. The southern border of the park is marked by Hadrian’s Wall, and some of the finest Roman sites in Britain lie within the park’s borders.This “land of the far horizons” is a scenic gem at the top of England, anchored by the Cheviot Hills and undulating southward in swaths of open moorland and grasslands, dotted with traditional villages and cut by picturesque valleys.Northumberland is justly famed for the ancient engineering marvel of Hadrian’s Wall. The wall was constructed in the A.D. 120s to mark the frontier of the Roman Empire and separate its lands from those of the barbarians beyond. Many centuries later, most of the turf-and-stone structure still stands, stretching across the landscape of Northumberland for 73 miles (117 kilometers). It can be walked end-to-end along the Hadrian’s Wall Trail.
