Liverpool was built on the river. In the 18th and 19th centuries it was one of the greatest ports in the world, the gateway between Britain and the Atlantic, rich from cotton, sugar and, until 1807, the slave trade, in which Liverpool ships carried well over a million enslaved Africans. Millions of emigrants left for America from its docks, many of them Irish, fleeing the famine of the 1840s, and others stayed: Liverpool has the oldest Black community in Britain, in Toxteth, and the oldest Chinese community in Europe. Sailors brought home the music, and in the 1960s four local boys turned it into the most famous music city on earth. Then the port declined, the city went through hard decades of unemployment, the 1981 Toxteth riots and talk in government of "managed decline", and it came back, as a European Capital of Culture in 2008 and host of Eurovision in 2023.
Liverpudlians, Scousers, are famously warm, quick and funny, and proud of a city that's had to fight for everything. It's compact, the center is walkable from the waterfront to the cathedrals, and five days give you the Beatles properly, both football clubs, the museums, most of them free, the pubs and a day in Roman Chester.
This plan starts on a Wednesday, because the city's national museums close on Mondays. Day one is the waterfront and the Mersey, day two the Beatles, day three St George's Hall, the Walker and Anfield, day four Chester, and day five, a Sunday, the two cathedrals and the Georgian Quarter.
