I just don't get the whole thing. Really? Would you like to hold your wedding at Bergen-Belsen? Birkenau? If that's too intense, how about Manzanar? Or hey, why not do that pricey photoshoot at one of the Gulags?
Admittedly, it's hard to find a famous architectural "treasure" that *isn't* the façade for some dreadful historical cruelty and injustice. When we admire e.g. the Sphinx and the Pyramids and the temples at Abu Simbel -- we're admiring millions of slave-hours of labour. From a far-off, distant historical perspective, of course. That Was Then, etc.
But imho that emotional statute of limitations, that distancing, hasn't nearly kicked in yet for plantation architecture; the despair and suffering of the enslaved population is barely outside living memory. Still fresh. Those "gracious" antebellum homes are haunted houses, every one. And the evil that those whitefolks did lives after them, still walks among us. That wasn't just Then, it's still Now.
So I ask myself, what kind of energy are you inviting into your marriage, to exchange your vows on the site of such recent enslavement, torment, and misery? With such a direct, such a linear connection to present pain, grief, injustice, terror?
