Ærial view. Doesn’t look so bad here, really. Old ROM appears to have been constructed around the new as a kind of brace.

Entrance view. Heads up! It could collapse at any moment! And note the angles. Now imagine ice, snow (solid or melted), and rain gaining speed on the way down. The inevitable homeless population huddling in the nook (to left of centre at ground level in photo) are goners for sure.

Southwest view. A bracket fungus colonizing a stone museum. The future parasitizing the past.
