A huge filming crane was spotted in the city centre this morning as filming continues for Sky Drama Cobra.
Exchange Flagsprovided the backdrop for film crews today specialist equipment was used to reach above the historic buildings.
The crews were back in the city to continue filming series two of Cobra, a drama starring Robert Carlyle.
This isn't the first time the production team used the city for filming, with Liverpool also providing the backdrop for the first season of the show.
Back in November, camera cranes and lighting scaffolding were also set up to shoot the series, which features The Crown star Victoria Hamilton and Richard Dormer from Game of Thrones.
It is not yet known how long crews will be filming in Liverpool for.
The series follows the British Government and its COBRA committee - and how they deal with national emergencies.
A spokeswoman for the series shared a synopsis of the second series with the ECHO, revealing what we can expect to see.
The spokeswoman said: "The lights may be back on, but the country’s troubles are far from over in series two of Cobra, written by Ben Richards.

"In the aftermath of both solar and political storms, Prime Minister Robert Sutherland (Robert Carlyle) attempts to steer the country on a more even course.
"He is assisted, as ever, by his loyal Chief of Staff Anna Marshall (Victoria Hamilton), alongside a team of dedicated advisers.
"An assassination on British soil, however, unleashes a chain of events that threatens to develop into a crisis even more serious than the one from which the country has recently emerged.
"An invisible global enemy, not playing by the rules and operating outside national boundaries, appears to be bent on our destruction, leaving an entire country unsure as to who is friend and who is foe."
