For a while there was confusion in the Perth venue scene due to the existence of both the Perth Superdrome and the Perth Superdome. Though both have since been renamed, it is interesting that such similar words with such difference origins should be used to describe such similar structures.
Drome is from the Greek Dromos, meaning race course or running track. It can be found in words such as hippodrome, a horse-racing course, and palindrome, a word that is the same running backwards as forwards.
