Holy Crown of Hungary

The Holy Crown of Hungary (also known as the Crown of St. Stephen) is located in the Hungarian Parliament. Ever since the 12th century, all of the kings of Hungary were crowned with the same crown excepts for three: Ladislaus I of Hungary, John Sigismund Zápolya, and Joseph II. The crooked cross at the top calls your attention immediately and it is believed that was added in the 16th century. This cross is currently tilted to the left and many believe that it was actually able to rotate up until around the 17th century.
