I think Sheffield is the highest city in the uk. I know Birmingham is pretty high up too. Interested in finding out!
Birmingham is situated just to the west of the geographical centre of England on the Birmingham Plateau - an area of relatively high ground, ranging around 150-200 metres above sea level
Sheffield: The city's lowest point is just 10 m above sea level, while some parts of the city are at over 500 metres (1,640 ft). However, 89% of the housing in the city is between 100 and 200 metres (330 & 660 ft) above sea level.
Just found the above stats on wikipedia, so id definatly plump for Sheffield as being the highest!
