On 10 December at 6.30pm the Tree of Remembrance will be lit up in Charlotte Square Gardens.
Before then you can donate to the Light Up a Life Appeal by making dedications and donations online.
This year, the hospice marks its 40th anniversary and with it, four decades of its Light Up A Life appeal.
More than 2000 people came along to the event last year, the highest attendance to date. The lights on the 40ft tree symbolise dedications which have been made in memory of people who have died, giving the tree special meaning to those who have made one to remember a loved one.
Charlotte Square Gardens will open at 5.30pm to spectators, with refreshments available courtesy of Starbucks. A local community choir will be singing Christmas carols and the ceremony will begin at 6.30pm with Sir Tom Farmer making a short speech, followed by the lights being turned on. The tree will remain lit up until Friday 5 January.
Everyone is welcome to visit the Gardens for the service and can also make a dedication if they would like to.
