A holy water font or stoup is a vessel containing holy water which is generally placed near the entrance of a church. It is often placed at the base of a crucifix or other Christian art. It is used in Catholic, as well as many Lutheran and Anglican churches, to make the sign of the cross using the holy water upon entrance of the church. Holy water is blessed by a priest or a deacon, and its usage by Christians serves as a reminder of their baptismal vows. The holy water font is a derivative of the cantharus, which has been used by Christians since the time of the early Church to perform ablutions before entering the church.
