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...
...is worth a thousand words. As you can see from the map, hydraulic power from the accumulator can be used to power things all around the harbour, including to swing Prince Street Bridge, about a mile away. Impressive.
I got interested in Bristol's medieval water supplies after poking around near Jacobs Wells Road and Brandon Hill. It was during that research I found out about a pipe that's still there today, and, as far as I know, still actually functioning, that was originally commissioned by Carmelite monks in the 13th century. They wanted a supply of spring water from Brandon Hill to their priory on the site of what's now the Bristol Beacon—Colston Hall, as-was. It was created around 1267, and later, in 1376, extended generously with an extra "feather" pipe to St John's On The Wall, giving the pipework its modern name of "St John's Conduit".
St John's on the Wall is still there, guarding the remaining city gate at the end of Broad Street, and the outlet tap area was recently refurbished. It doesn't run continuously now, like it did when I first moved to Bristol and worked at the end of Broad Street, in the Everard Building, but I believe the pipe still functions. One day I'd like to see that tap running...
There are a few links on the web about the pipe, but by far the best thing to do is to watch this short and fascinating 1970s TV documentary called The Hidden Source, which has some footage of the actual pipe and also lots of fantastic general footage of Bristol in the seventies.
On my walk today I was actually just going to the building society in town, but I decided to trace some of the route of the Carmelite pipe, including visiting streets it runs under, like Park Street, Christmas Street, and, of course, Pipe Lane. I also went a bit out of my way to check out St James' Priory, the oldest building in Bristol, seeing as it was just around the corner from the building society.
There are far too many pictures from this walk, and my feet are now quite sore, because it was a long one. But I enjoyed it.
