It seems a bit perverse to continue posting about museums and architecture without referring to the fact that I, like everyone else in the world, have spent the last few days glued to the radio and twitter watching the current world order collapse: the belief that war in Europe could, and would, never happen again because of the collapse of the USSR and the end of the Cold War. It seems a bit strange that even a week ago it was assumed that Putin would not be so reckless as to invade, whereas now everyone takes it for granted that it was obvious he would. And, like everyone else, I have been watching with wonder and admiration the bravery of individual Ukrainians who have been so overwhelmingly determined to arm themselves, to resist and to fight in defence of their country, not to mention the heroism of their President.
