User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-5020152-20121004003954

I think there was a (much) earlier debate about where the Tower is located, since it can be accessed in both MHFU and MH3U.

My theory is that they are two different, but identical, structures. If they were used for religious purposes, it's possible that the tribe or clan that made them traveled to Moga and decided to build another one, so that they could carry out their rituals no matter where they happened to be.
