'That roof' presumably referring to the train station, in which case WOW!
Was'nt it exquisite, and for once it wasnt crudly utilitarian with great beams visible etc, it was delicate & light and spectacular at night.
Its one of the most beautiful modern structures I've ever seen.
It's interesting how not a million miles away it is from a lot of our Victorian roofs at stations, elegantly perched atop columns which flow into each other via curved brackets.
(Admittedly I was half unconcious towards the end as well)
