Found this snippet on Wikipedia,
Formed in 1888 as Medindie, in 1893 the club renamed itself to North Adelaide. It is the fourth oldest club still in operation in the SANFL. Although several other early clubs used the name of "North Adelaide", none of them bore ties to the current club[1].
North Adelaide started playing at Prospect Oval in 1922 and it has remained their home ground ever since.
Which leads to my question of where was the home ground of North Adelaide prior to 1922?
