>Why the pisa tower cross?
Which version do you wanna hear?
Nevermind, I'll write what I can.

So.
We have no idea why does it stand askew, but many theories were created by both historians and the people. If one observes the Crown it will be apparent that not just the cross strange but the crosspiece and the rim are also seems to be deformed which can lead to the easy conclusion it was hit with large force from above.
Here are some ideas:
1. In 1301 the House of Árpád went extinct on the male line and three candidate from female line wanted the throne to himself. One of them, the Bavarian Otto acquired the Crown, and came into the country in 1305. He brought it with him:
a. The put it in a big wooden flask but during the road it fell off the horse at one point and they had to search for it. The drop damaged the Crown.
b. They put it in a small barrel but it was too small and when they put the lid on it pushed down the Crown.
This version is based on the story of the chronicle and the two version comes from the two possible translation of a Latin word. The chronicle doesn't say however that the Crown was harmed, so it is a speculation. Also this is one of the versions what usually was cited as a reason.
2. In 1849 the War of Independence was defeated and the governor, Kossuth, fled to Turkey. He had the Crown but didn't want to bring it with him to abroad. So they buried it at Orsova. I think it was underground for four years. Somehow it was damaged either when it was buried or when recovered. This is also a popular version.
3. In 1638 during the coronation of queen Mária Anna (first wife of king Ferdinand III.) they got the wrong key for the reinforced chest they guard the Crown in. They had to break this chest and had to use large force and they dun goofed. (Btw, during Habsburg times the queens were crowned with another crown, the Holy Crown was only used to touch their shoulders.) This version is fairly recent one.
4. This isn't the original cross, but a replacement which was mounted in the 16th century.
a. A version says that in 1551 queen Izabella break the original one down and gave it to his son, king János II (aka János Zsigmond), who wore it in his neck on a chain. They surrendered it to king Rudolf I. but it's further fate is unkown. The Habsburgs made a new one instead.
5. There was no cross originally, it was mounted later (for example in the 16th century).
