"It's the Grand Central complex in Stockport, Greater Manchester. It's a grotty, whiffy sort of low-intensity leisure & business area, and is supposed to be due for demolition so they can replace it with something even worse, but we love the roundel. The top semicircle has a representation of the railway viaduct over the River Mersey, and underneath is a bowling ball and wavy lines for the bowling alley and HIDEOUS swimming pool."
Then on their travels further afield:
Richard writes "This one's in Mallorca, about one-third of the way between Palma and Soller, on the railway. I haven't a clue what goes on in there, our train didn't stop there, but it was great to be surprised by a roundel while abroad!"
One much closer to home from Mark: "This one must have been around for a while 'cos I passed it yesterday but being without camera found it on Google StreetView. It says 'Finchley & Totteridge'."
Moving further afield Anno Superstar spotted the roundel in a record shop in Stockholm
Finally, thanks to Rebecca Caroe for spotting this in Dunedin New Zealand
Many thanks to all for being so observant and if you have any pictures of roundels seen in odd places outside of the London Underground, please send them my way and I'll blog the best. Until next time the full collection of Tube roundels outside their home is here.
