I always find it fun when soap life sort of intersects with real life (however obliquely), and the chance came again in the 16 Mehefin 2016 episode (still available at time of writing):
As part of his running battle with Meical and Michelle, Arthur decides to "lose" a parcel he is supposed to deliver to them. We get a nice shot of the address:
Meical Samuel Williams
4 Lôn Pen Nebo
Now, we've come across that postcode before on parcel labels (Arthur has form for this kind of thing), and if you feed it into Google maps / streetview, it is slap bang at the set of Round a Round in Dale Street. Now according to
...this street is also known as "Cilbedlam". (Although on the street sign you can see in streetview, it has another name).
However, I had a nose around with streetview, and if you look near the end of Hill Street (which is not far from Dale Street, you see a street sign which bears both the English name of Dale Street, and the Welsh name: "Lôn Pen Nebo", and if you move the viewpoint up the street a bit: bingo! you find the row of houses where Meical/Michelle, Iris/Arthur, and Vince/Cathryn all live; very recognisable when you see them, but I'd never been able to find them (on streetview) before.
(Would now like to find the houses of: David, Wyn, Llio/Iolo/Carys, Terry/Glenda/Sophie).
