Ex1. What is your most memorable/unforgettable stadium?
Why is the stadium so memorable for you?
Ex2. What was your most memorable/unforgettable?
Why was the stadium so memorable for you?
Q. Should the tense be in past tense even if the object (stadium) is still the most memorable/unforgettable?
Thanks in advance.
In this case, the tense doesn't matter much. Both are intelligible and acceptable in my opinion. In most contexts I prefer the present, but you might choose the past if you were interviewing a famous but retired footballer, and the present if he was still playing.

It might also depend on whether the stadium still exists- if you were asking about the old Wembley stadium, the past tense would be the natural choice.
