Ha ha! Yes, if you look at Greenwich observatory in Google Earth, the waste 
bin - at the junction of two foot paths to the East of the Flamstead 
building - can be clearly seen. The bin was obviously placed for 
convenience at the junction of the two footpaths, rather than to mark the 
GPS version of the Prime Meridian. :-)
