River Liffey

The River Liffey passes through central Dublin and is fed by the rivers Dodder, Poddle and Camac. It's a big river, but it's famous because it is the natural divide of the city. To the north, you have the commercial and industrial districts as well as some more run-down neighborhood which are best to avoid at night. To the south, you have the neighborhoods of Trinity College, Temple Bar, and everything is a bit more posh. The Liffey has been used since the time of the Vikings to take products from the interior to the sea and then export them abroad. During the industrial revolution, the Liffey was used to transport Guinness to the United Kingdom and other countries of the British Empire.
