There are five bells in its bell tower, collectively nicknamed The Pompey Chimes, as they inspired the football chant of the same name.
The largest of the five bells, Victoria is named after Queen Victoria and is inscribed with her name, and chimes on the hour.
The four quarter bells chime at 15, 30 and 45 minutes past the hour and play the Westminster Quarters, just before Victoria tolls on the hour.

The Pompey Chimes fell silent in 2003 when the bell tower was found to be in need of restoration from the corrosive nature of sea salt in the Portsmouth air.
The work was carried out by Smith of Derby Group, the restoration project finishing in time for Queen Elizabeth's visit to Portsmouth in 2009 to mark the 65th anniversary of the D-Day landings.

The four quarter bells were to have been officially named Nelson, Victory, John Pounds and Harry Redknapp in a 2008 public poll by Portsmouth City Council in 2008.
The official naming was stalled due to the high popularity of internet votes for Harry Redknapp's name from unregistered anonymous voters.
Redknapp, the former Portsmouth Football Club manager had suddenly departed the club for Tottenham Hotspur F.C. shortly before bell name voting commenced, which had left a wide range of emotions among many Portsmouth Football Club fans and city residents.
Foul play, possibly from rival football supporters was suspected by Portsmouth City Council, who had organised the vote, and the four quarter bells have remained unnamed.
