Cyber security consultant James Metcalfe picked our city as his specialist subject in an episode of the BBC quiz show which aired on Monday, February 15.
He was asked a range of questions about Portsmouth’s past, including about an assassination, a duel and a shopping centre.
We have pulled together a quiz so our readers can test themselves and see if they could score better than James’ 7 out of 10.
A word of warning – some are very tricky!
Enjoy the quiz and find the answers on the final page of this gallery.
Let us know how many you got right.
