If you're still pondering what to do with your weekend, you could do a lot worse than a visit to the Brunel Museum in Rotherhithe. The tiny museum is opening its 'secret' shaft chamber at weekends for a bit of chthonic Christmas cheer. We wouldn't normally copy and paste, but their words say it all perfectly:
Descend by short tunnel and temporary staircase into a secret chamber, half the size of Shakespeare’s Globe, for a Christmas gift and adventure. Celebrity stories penned by Michael Palin, Zoë Wanamaker, Peter Ackroyd and Jo Brand, all told underground by the light of Boggett’s patent prismatic reflectors and in the shadow of the celebrated bottle pantomimic equilibrist…
Quite. We've been down there and, frankly, they're under-pricing themselves at £5 (which also includes admission to the main museum). Turn up Saturdays for 2pm, 3pm or 4pm, or Sundays at midday up till and including Christmas Eve.
