I would prefer to hear about the more modern architecture and how these buildings came to be built. In the historical era I am sure those with money just built them whereas there are now far more things to be considered and overcome. Also provokes discussion on whether a building will stand the test of time to become 'historical'
I can just imagine the conversation - Viking 'Clay, would you be able to be a guest lecture on (insert) Viking cruise? Clay 'i'll need to think about that, oh go on then'
