Nobody has attempted to identify this quay, so the competition is now closed and I’ll drink the sherry myself.
It is, of course, the downstream quay at Clarecastle at the head of the Fergus Navigation.
Here is the upstream quay, just around the corner.
The upstream quay bears the following inscription.
I really must return and get a better photo when it’s less slippy. Note that, although this is on tidal waters, Thomas Rhodes was the engineer.
Did you know that Clarecastle still has its own port authority? Go to this excellent pub and ask John Power about it. His brother (Dr Joe) wrote the definitive history of Clarecastle. John has lots of interesting old photos and maps on display in a really good traditional pub. He’s got a facetweet thingie too.
