"The Maltese cross is a cross symbol, consisting of four "V" or arrowhead shaped concave quadrilaterals converging at a central vertex at right angles, two tips pointing outward symmetrically.
It is a heraldic cross variant which developed from earlier forms of eight-pointed crosses in the 16th century. Although chiefly associated with the Knights Hospitaller (Order of St. John, now the Sovereign Military Order of Malta), and by extension with the island of Malta, it has come to be used by a wide array of entities since the early modern period,
notably the Order of Saint Stephen, the city of Amalfi, the Polish Order of the White Eagle (1709), the Prussian order Pour le Mérite (1740), and the Bavarian Military Merit Order (1866)." - (en.wikipedia.org 25.08.2021)
