The £72m Museum of Liverpool, which opened in July, has revealed that it will open its new ground floor Great Port area and a first floor boasting three more galleries on 2 December.

Denmark-based 3xN were behind the design of the attraction, which already incorporates the Atrium and the Global City, Little Liverpool, Wondrous Place and Skylight galleries.

The Great Port on the ground floor will explore Liverpool's history on the River Mersey and uses exhibits from National Museums Liverpool's land transport collection to tell the story.

On the new first floor, visitors will be able to examine the Liverpool Overhead Railway, which was demolished 55 years ago but has been revived to be sited over the Great Port gallery.

Other galleries to open on the first floor will include City Soldiers, dedicated to the history of the King's Regiment. The History Detectives gallery will provide a background to the city.

Museum director Janet Dugdale said: "Aside from The Great Port on the ground floor, we are also opening up the entire first floor of the Museum which includes the Liverpool Overhead Railway gallery and two more special galleries.

"History Detectives will focus on the history of the area from the Ice Age to the present day, and the second will explore Liverpool's special relationship with one of Britain's oldest regiments, the King's Regiment."
