Liverpool Docks

Liverpool Docks were located on the city's waterfront, adjacent to the Mersey.

On 31 October 2021, just after the Three Minute Eclipse, Sontarans appeared at Liverpool Docks, from where they took over the whole waterfront. The docks were used as a base by Sontaran Temporal Command, who built Imperial Sontaran Time Carriers, so that they could travel back in time to to invade Earth's past and fight in the Crimean War.

Dan Lewis infiltrated Liverpool Docks and, with the help of Karvanista, created a temporal reaction which erased the Sontaran invaders from history. (TV: War of the Sontarans)

Behind the scenes
As a major port, Liverpool has a number of docks. However, shares the most resemblance to the docks shown in War of the Sontarans. Indeed, the crane in the episode is emblazoned with the initials "ABP".
