An Evening Wander to the Gallows
06 Apr 2021
I'd originally intended just to pop up to the area around Alma Road, where I'd missed a few streets on earlier wanders. It was such a nice evening, though, I decided to extend my walk up to the very top of Pembroke Road, just outside my one mile radius, to take a few snaps of something intriguing I'd found in my researches.
I've driven, walked and jogged past the little triangle of land at the top of Pembroke road a great deal in my time in Bristol, but I didn't know that it used to be the site of a gibbet, in fact that the road itself there used to be called Gallows Acre Lane. According to the Durdham Down history trail, by Francis Greenacre (an excellent name for a Downs researcher!) among other sources:
...it was below this quarry near the top of Pembroke Road, once called Gallows Acre Lane, that a gibbet stood. It was sometimes occupied by those who had committed robberies on the Downs and was last used in 1783 to hang Shenkin Protheroe for the murder of a drover. Stories quickly spread that he descended from the gibbet at midnight every night and stalked through Clifton. Such was the alarm that his body was cut down
and buried.
Also very close to this little triangle of land was one of the gates of the extensive turnpike system...
Anyway. Along the way I encountered a wooden tortoise and a real squirrel, among other things. It was a good walk, and more light in the evenings means I can move my wanders out of the ticking countdown clock of work lunch-hours and be a bit more leisurely.
I'm afraid that this is a bit of a badly-curated wander, where I mostly just popped out to find out a little of the history of Underfall Yard and poke around the various open workshops, and, in hindsight, really didn't take pictures in any kind of coherent order. So there's a lot of pictures, but they don't really tell the story that, in hindsight, I seem to have been trying to tell, of the unusual electrical substation in Avon Crescent, the Bristol Electricity that predates the National Grid but is still in use, the history of the hydraulic power house... It's a bit of a mess.
But I suppose sometimes these wanders—always chronologically presented in the order I walked and took photos—simply will sometimes be a bit of a mess. Let's hope you still get something out of it, anyway...
It's very hard to get a decent look at this building. This is the top half of the back of it.
This building is, or was, an electrical substation. I heard an unconfirmed rumour that the building itself is now actually empty, and that the entire substation guts are now in these boxes. I have no idea whether that's true or not.
You can see this once apparently bright and airy building has had every window bricked up.
I understand that something in or around this building still supplies the odd electrical requirements (specifically, 360V "Bristol voltage") for some bits of Underfall Yard, which is our next stop, so more about that when we get there.
While it's not a listed building, is is notable: it's one of the earliest reinforced concrete buildings in the UK, apparently, construction starting in 1905. I assume it was up by 1907, as that's when Undefall Yard installed their electric pumps.
This oddity of history predates the National Grid and was originally fed from Feeder Road power station (well, Avonbank, on Feeder Road, to be precise. We've seen a bit of that history before, as a line marker for the line from Portishead to Feeder Road.) It was connected to Feeder Road by 1906, with a 6,600V line.
I've added a couple of historic views of the building as the next two photos in the wander, but I'll also pop this link to a Loxton drawing of the Avonbank electricity works, 1908 here.
Via this Tweet and taken from KYP Bristol, showing the interior with a couple of Westinghouse rotary converters and a Peebles-La Cour motor converter, assuming this picture ties up roughly with this 1908 Institute of Mechanical Engineers' visit to works.
You can see a picture of similar Westinghouse converters to the two at the back in the Wikipedia rotary converter page and a Peebles converter that looks very similar to the one in the foreground on the cover of the Peebles motor converter catalogue in the sidebar of their entry in Grace's Guide. I'm guessing the additions on the ends of the Westinghouse converters were for different voltages? A rotary converter is basically a motor connected to a dynamo, so extra dynamos with different windings would give you different voltage outputs, I suppose, but I know very little about power generation.
And here's the Loxton picture of the exterior, from the Bristol Libraries collection. Seems such a shame to have bricked up those lovely windows.
Bower Ashton is an interesting little area just south of the river from me—in fact, the Rownham Ferry used to take people over from Hotwells to Bower Ashton, operating from at least the twelfth century to around the 1930s.
It's a strangely contradictory little area, with a cluster of old and new houses sandwiched in between the busy A-roads and significantly more industrial area of Ashton and the bucolic country estate of Ashton court roughly east to west, and also between Somerset and Bristol, north to south.
I've been around here before, mostly poking around Bower Ashton's arguably most well-known bit, the Arts faculty campus of the University of the West of England, but I'd missed at least Parklands Road and Blackmoors Lane, so I initially planned just to nip across briefly and wander down each in turn. On a whim, though, I texted my friends Sarah and Vik in case they were out and about, and ended up diverting to the Tobacco Factory Sunday market first, to grab a quick flat white with them, extending my journey a fair bit.
To start with, though, I nipped to a much more local destination, to see something that you can't actually see at all, the Gridiron...
(I also used this wander as a test of the cameras in my new phone. I finally upgraded after a few years, and the new one has extra, separate wide and telephoto lenses compared to the paltry single lens on my old phone. Gawd. I remember when speed-dial was the latest innovation in phones...)
That's quite some hefty kit. I presume the nearer thing is a heat exchanger for the transformer. Certainly a different look from the last substation I remember snapping.
Bedminster Trip for New Walking Shoes
26 Feb 2022
I needed to buy new walking shoes—my old ones were squeaking and it was driving me up the wall—so I ordered some for collection from Taunton Leisure on East Street in Bedminster, and decided to make picking them up an official wander.
I didn't cover any new ground within my mile, but I did take advantage of the trip to take in a few interesting things just outside my normal radius, mostly New Gaol-related. Along the way there are a couple of sanitation-related diversions, including a visit to a rare manhole cover. You can hardly wait, I can tell!
The traditional double-doors-in-the-pavement-and-vent-pillar combo that marks a subterranean electrical substation in Bristol.
