[spoilers] Spooks Locations

[Tea Lady]

If anyone can spare a few minutes to give me a second opinion on something I would be most grateful. I am trying to find the location of the park from 8.8

Spoiler: show

where Ruth meets the chinese bloke

As Ruth enters the park through the walled garden there is a sign to her right about walking dogs. On the top of the sign is the coat of arms for the London Borough. It is not a great shot but you can just make out the colours, a red and white shield (I think it is a shield) a blue figure to the right and an orange figure to the left. I have looked up the coat of arms for London Boroughs on the net and the closest I can match it to is Southwark. This would seem to make sense as they have done filming around that area before. But there also appears to be writing around the coat of arms, 5 letters to the top and 7 below. The only London Borough with this amount of letters in the name is Tower Hamlets. Their coat of arms is totally different though. If anyone can have a look and see if they think it is Southwark as well.
