The Merseyside Marine Museum opened in 1980. It vividly tells the story of the sailing history of Liverpool with a large number of pictures. The Museum has four floors and has many exhibits on immigration, slave trade, World War II and shipbuilding history. After visiting the exhibition hall, you can see the four floors of the museum, where you can see the scenery of the downtown area of Liverpool. Every Tuesday and Wednesday, at 10:30, 11:30 and 14:30, there are free guided tours of old wharf sites, which are situated underground in Liverpool One and must be booked in advance. The history of trade in Europe is the history of human catastrophe. From Africa to Asia, it is a bloody history.
