I kinda agree that it could be a monument of their "primitive" days prior to becoming technologically advanced. They had a museum where they displayed their past achievements. I'm pretty sure that they'd atleast preserve some of their historic buildings and display them for tourists (like we modern folks do now).

That or it could be Meracydian in origin and we know that Miqo'te lived there prior to the 5th Astral Era and that it was the Seeker of the Sun that worshipped Azeyma
