Though not a current national flag, the banner of the Crusader Kingdom of Jerusalem during the 13th century featured the Jerusalem cross. This consists of a large cross potent (or a "crutch cross") surrounded by four smaller Greek crosses, one in each quadrant. It is considered to be a symbolic depiction of the five wounds of Christ. The Jerusalem cross today remains the emblem of the Equestrian Knights of the Holy Sepulchre.
