Ground with the most number of World Cup matches??

The ground that has hosted the most number World Cup matches is in England which would come as no surprise considering England has hosted 4 World Cups in 1975, 1979, 1983 & lastly in 1999. Mostly our guess would be Lord’s, London, since our victory in 1983 over there is still fresh in our minds, actually Lord’s has hosted 10 games and 4 of them finals but the right answer turns out to be Headingley, Leeds where the most matches have been played which is 12.
Here is a list of the matches played at Headingley:
1975 (3) Aus won 73 runs vs Pak, Ind won 10 wkts vs EA, Aus won 4 wkts vs Eng
