The Mall teamed up with Luton Town Centre Chaplaincy and St Mary’s Church to hold a service for the launch of The Prayer Tree on Sunday, December 7.
The Tree has been a Christmas custom in the shopping centre since 2008.
A spokesperson for The Mall said: “It is often easy to lose sight of the importance of Christmas and the real reasons why we celebrate it.
There is a basket of decorations next to The Tree each with a prayer attached and space for a name to be added.
Shoppers choose a bauble, dedicate it to someone and place it on to the tree, they will be collected on Christmas Eve and read out at Midnight Mass.
