Jerusalem Cross is a heraldic cross and Christian cross variant consisting of a large cross potent surrounded by four smaller Greek crosses, one in each quadrant. It was used as the emblem and coat of arms of the Kingdom of Jerusalem from the 1280s.
There are variants to the design, also known as "Jerusalem cross", with either the four crosslets also in the form of Crosses potent, or conversely with the central cross also in the form of a plain Greek cross.
It is not to be confused with the Lorraine cross, which has also been called the "Jerusalem cross"
While the symbol of the five-fold cross appears to originate in the 11th century, its association with the Kingdom of Jerusalem dates to the second half of the 13th century.
The symbolism of the five-fold cross is variously given as the Five Wounds of Christ, Christ and the four evangelists, or Christ and the four quarters of the world. The symbolism of five crosses representing the Five Wounds is first recorded in the context of the consecration of the St Brelade's Church under the patronage of Robert of Normandy (before 1035); the crosses are incised in the church's altar stone.
