The Dublin church which houses the bones of St Valentine will today host ceremonies to bless the rings of its congregation.
A casket containing the remains of the patron saint of lovers will be taken from a shrine in the Carmelite Church in Whitefriar Street and placed on the high altar for the annual custom.
Prior of the Carmelite monastery, Fr Christopher Crowley said that wedding, engagement and friendship rings of 'special sentimental value' will be blessed during the service after Masses at 11am and 3.15pm.
Fr Crowley said St Valentine's Day is marked all over the world but not many people know that his remains rest in a Dublin church.
"We get a trickle of tourists during the year but I suppose it is still a very well-kept secret."
St Valentine's remains have rested in the Carmelite Church since 1836 when they arrived in a sealed reliquary from Rome.
The oratory also contains a statue of the saint, under which couples often propose marriage to each other, according to Fr Crowley.
