Liverpool..
When you think of Liverpool, you probably think of The Beatles, Liverpool Football Club, and their illustrious Anfield stadium, which is unquestionably one of the most significant in the country. There is also the exceptional Scouse accent, of course. The eastern bank of the Mersey estuary acts as Merseyside's geographic core. The Mersey is over a mile broad and empties into a basin that is three miles wide. Liverpool has one of the biggest ports in the world and is not tide-dependent.
