Maybe I'm getting less patient with this quiz but it has left me stumped this week. I think the answer to Q2 is Bow Creek, referring to the Blackwall Thames Ironworks where HMS Warior was built but Q1 (name of the cavernous building) suggests Saint Pancras Station. Anyone solved it yet?
I'm stumped too. Thought at first it was Charing Cross, though St Pancras now seems more likely. (Can't confirm the 285 ft wide bit, though). You've got further than I have on the creek.
Not the gherkin, I'm not saying because - unlike crosswords - this is like an adventure and needs a lot of work (a lot more than just Googling a clue).
Sorry, I'm being particularly thick - I really can't find the answer to the name of the cavernous building despite your clues and I've been looking all morning.
Well, this one got us all going. Thanks to wideboy I have worked it out as the Excel Exhibition Centre. This is what comes of having an out-of-date Rough Guide.
