Consecration crosses are crosses on the interior walls and exterior architecture of a Christian church or cathedral showing where the bishop has anointed the church with chrism or holy water in order to consecrate it. There is often a place for a candle in front of each cross which is lit on the anniversary of the consecration. The crosses signify the sanctity of the church. The 13th-century Trinity Chapel in Salisbury Cathedral contains a painted consecration cross dating from 30 September 1225.
