Liverpool will fall silent for a minute to mark the 30th anniversary of the Hillsborough disaster.
Ninety-six lanterns were lit on Monday morning on the steps of St George’s Hall in tribute to those who died.
Banners with images of the 96 fans killed by the crush at an FA Cup game have also been hung at the hall.
A minute’s silence will be held across the city at 15:06 – the time the 1989 FA Cup semi-final between Liverpool and Nottingham Forest was stopped.
City mayor Joe Anderson and Lord Mayor, councillor Christine Banks, laid wreaths in front of the lanterns to begin the day of remembrance.
The message on Mr Anderson’s wreath reads: “Never Forgotten. Reds and Blues united.”
Flags on civic buildings will be flown at half mast and the bells of the Town Hall will toll 96 times.
At Anfield, Liverpool FC chief executive Peter Moore placed a wreath at the Hillsborough memorial as club chaplain Rev Bill Bygroves conducted a brief service with members of the under 23 squad.
A memorial service is due to be held at Liverpool Cathedral at 14:45, while The Kop will be open between 13:00 and 16:00 for people who want to sit and reflect.
