Blue railings

Well, I don't recall as it seems so long since you've been there!
And I never did understand the rules (of MC, I mean, not gwl) although I do have the vague impression that you're not supposed to...
For now, I'll say Borough - try another one.

We might eventually have a HoF here! (Hall of Fame - for frequently appearing pics for those who are new to this game...)

so if I'm understanding this correctly, this picture is from a street that Adrian mentions often, so much so that it has become the Mornington Crescent of GWL (I had to google that 'mornington crescent' reference.... ;-)) but it is neither Mornington Crescent, nor in that other street, nor... in Borough... I'm confused... Lol (just kidding, I have no idea anyways!) It's a church I think...

Yes, I think that about sums it up...
Your are right it is *not* in Mornington Crescent, or Borough or the same borough as Mornington Cres. But it is a former church and nearish to a couple of others I have had in the pool recently.

It's all very confusing...
See Wikipedia
Now I read it again it seems that Whitefield's tabernacle was a wooden building but the 'church' (denomination unspecified) was rebuilt in stone (current building) in 1868. Now I need to look for the foundation stone mentioned in the Wikipedia article. No date in that article for when it was taken over by the school. A ref to Pevsner but I don't have that vol.
No mention of Magistrate's court in WP... (not that I trust it as a definitive reference.)
On the list for further clarification.
PS. Congratulations on the point!
