Given the question: Information: - Southern England, or the South of England, also known as the South, refers roughly to the southern counties of England. The extent of this area can take a number of different interpretations depending on the context, including geographical, cultural, political and economic. - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. - York Castle in the city of York, England, is a fortified complex comprising, over the last nine centuries, a sequence of castles, prisons, law courts and other buildings on the south side of the River Foss. The now-ruinous keep of the medieval Norman castle is commonly referred to as Clifford's Tower. Built originally on the orders of William I to dominate the former Viking city of York, the castle suffered a tumultuous early history before developing into a major fortification with extensive water defences. After a major explosion in 1684 rendered the remaining military defences uninhabitable, York Castle continued to be used as a jail and prison until 1929. - In anthropology and geography, a cultural region, cultural sphere, cultural area or culture area refers to a geographical area with one relatively homogeneous human activity or complex of activities (culture). These are often associated with an ethnolinguistic group and the territory it inhabits. Specific cultures often do not limit their geographic coverage to the borders of a nation state, or to smaller subdivisions of a state. Cultural "spheres of influence" may also overlap or form concentric structures of macrocultures encompassing smaller local cultures. Different boundaries may also be drawn depending on the particular aspect of interest, such as religion and folklore vs. dress and architecture vs. language. - Duke of Northumberland is a noble title that has been created three times in English and British history, twice in the Peerage of England and once in the Peerage of Great Britain. The current holder of this title is Ralph Percy, 12th Duke of Northumberland. - Northern England, or North of England, also known as the North or the North Country, is the northern part of England and one the country's three principal cultural areas, along with the Midlands and Southern England.

It borders South East England, South West England, North West England, Yorkshire and Humber, East of England and Wales.
