The coat of arms of Malta was created in the 20th Century but has an older history.
Every city in Malta has its own coat of arms. Each has a mural crown with three or four turrets. The capital Valletta, and the former capital cities of Mdina and Birgu have four turrets, while the rest have three.
The villages also have similar coats of arms, but without the mural crown.
