The Maltese cross is identified as the symbol of an order of Christian warriors known as the Knights Hospitaller or Knights of Malta. It was originally the symbol of Amalfi, a small Italian republic of the 11th century. The cross is eight-pointed and has the form of four "V"-shaped arms joined together at their bases, so that each arm has two points. Its design is based on crosses used since the First Crusade. The eight points are said to symbolise the chivalric virtues:
The Maltese cross remains the symbol of the Sovereign Military Order of Malta and other Orders of St John, and St. John Ambulance. In recent centuries it has come to be adopted as the insignia of numerous orders of chivalry, and appears on the coat-of-arms of the Mecklenburg-Strelitz district. In Australia the Maltese Cross is part of the state emblem of Queensland.
In the United Kingdom, the Maltese Cross is the symbol used by Rifle Regiments, and has been incorporated into the badges of virtually all rifle units, including the amalgam, The Royal Green Jackets. The first postmark employed for the cancellation of the then new postage stamps in the 1840s was the shape of a Maltese cross and named accordingly. The Maltese cross also forms the basis for the design of the Order of the Bath. The Maltese cross is also the symbol of Neath Rugby Football Club in Neath, Wales.
In Sweden a Maltese Cross forms the basic form for all Royal Orders, such as Order of Seraphim and the Order of the Sword.
In Australia the Maltese Cross forms the logo for South Australian Ambulance Service logos.
The Maltese cross flower (Lychnis chalcedonica) is so named because its petals are similarly shaped, though its points are more rounded into "heart"-like shapes. The Geneva drive, a device that translates a continuous rotation into an intermittent rotary motion, is also sometimes called a "Maltese cross mechanism" after the shape of its main gear.
It is considered one of the National symbols of Malta and used to be depicted on the two mils coin of the island prior to the removal of that denomination from circulation. It is now shown on the back of the one and two Euro coins which Malta introduced in January 2008.
