From Durham by car north, to Newcastle, compared to Durham Village, Newcastle is a big city, at Durham Railway Station, I also saw several students who went to Newcastle to eat, the train arrived in about ten minutes. Here I actually saw the wall, the Great Wall of Hadrian, in fact, this is the northernmost border of the Roman Empire's British province, and there is a similar work with China's wall, which is to defend against the northern invasion. Along the Tyne River from west to east is the entrance to the sea. The King of England built castles, made of wooden spires and earthen exterior walls. The new castle is the source of Newcastle's name.
