Jersey Flag
 
Flag Description:
white with a diagonal red cross extending to the corners of the flag; in the upper quadrant, surmounted by a yellow crown, a red shield with three lions in yellow; according to tradition, the ships of Jersey - in an attempt to differentiate themselves from English ships flying the horizontal cross of St. George - rotated the cross to the "X" (saltire) configuration; because this arrangement still resembled the Irish cross of St. Patrick, the yellow Plantagenet crown and Jersey coat of arms were added
