Sixty couples have renewed their wedding vows for Valentine's Day beneath a giant illuminated model of Earth, at the church where they originally tied the knot.
The mass ceremony at St Chad's in Kirkby will include couples old and young - from one who have been married for more than 50 years to those who wed in 2019.
Roy and Diane, who have been happily married for over 56 years, met when they were in the Christmas choir. They also had a welcome tip for couples on having a happy marriage.
Gordon and Debbie, who have been married for nearly 38 years, were teenage sweethearts.
They worked at the local Post Office and exchanged Valentine cards via the mail bags Debbie was responsible for.
Reverend Philippa Lee, Vicar at St Chad's, explained how couples renewing their vows can strengthen relationships.
Liverpool City Region Metro Mayor Steve Rotherham and his wife Sandra also renewed their vows.
Mr Rotherham said: "As a Kirkby lad, I know of hundreds of people who have tied the knot in St Chad's over the years - including myself and my wife Sandra back in 1989.
"After everything we have been through in the last 18 months, I am certain that there are many couples out there who would jump at the chance to do something a bit different."
Organisers are hopeful others, who have not yet said their vows, will decide to propose beneath the giant 'Gaia' artwork.
The illuminated planet is part of Knowsley Council's celebrations of its status as the Liverpool City Region's Borough of Culture for 2022.
