Thanks OG. We watched one episode, the one about Uzbekistan. Very interesting, but it looks we missed the others. We can't get iPlayer here, but I will have a look on Catchup.
We're spoilt for history shows, at the moment. I think I missed the first five mins of Episode 1 and it sounds like I've missed Episode 2 but will iPlayer it.
And the prize for weirdest looking city walls goes to....? (I misheard the commentary).
