While this is super cute, the notion that the ceremony hall has never been used before is incredibly baffling. Was there some kind of ban on using the hall? Why was it constructed in the first place, if not to be used?
Notre Dame took 100 years to build. St. Peter's Basilica took 120 years to build. This building looks like a blend between neoclassical style and gothic style, so it'd be weird if it was planned that way and built in a day. Did someone start building this thing decades before either of these two were born specifically for them, or did they magic it into being?
