Where Am I? No. 235 - Coast Scene

[despair]

I've just found that the image I used for the "geology matching" was not from  the Porth Island inlet,but Mawgan Porth,so I'll look for some images there.

I also thought lighthouses last night but felt the ''rock'' was too small. The foghorn makes more sense for that space.

Looking at Anglesey Light house we see similar wall/path structures. And we see a suspension bridge connecting the stack.



What would be this distance to the mainland? ie I looked at Looe Island ( St Georges) but dismissed it.

I'm very doubtful about the foghorn theory. A google image search suggests they are almost invariably located on top of a substantial concrete structure, if not on a lighthouse itself. If a foghorn had been located on top of the rock (and subsequently removed) then there would still be some kind of structure there. The alternative - that the foghorn is on the far side of the rock (so not visible in the picture) would mean that the headland acts as a sound barrier. The objective of the foghorn is to radiate sound out as far as possible, so 'hiding' it behind a rock facing towards an opposite shore would make it more or less ineffective.

I suspect in the Mull of Galloway example, the light is located as high as possible to maximise visibility, and the foghorn has been located nearer the sea to improve the distance the sound is carried. I'm not absolutely sure, but I believe sound is attenuated to a far greater extend over land than it is water, so placing it as close to the shore as possible maximises the carry. However, the semi-circular support arrangement in the Mull of Galloway example I think demonstrates the need to be able to 'swing' the foghorn from side to side so it can be heard from all seaward directions.

Another google image result is Mull of Kintyre - http://www.geograph.org.uk/photo/1877136

This illustrates the kind of structure used to raise the level of the horn, but more importantly illustrates the kind of safety provision I've referred to in previous posts. Contrast the 'sheep wire' fence at the Mull of Kintyre to the solidly built walls next to the bridge we are interested in. The 'sheep wire' is sufficient because the trained lighthouse keeper knows not to lean on it to get a better view... something you cannot rely on the public not to do!

If it turns out to be a lighthouse, just out of the photo shot,  then the rock could contain the jetty by which supplies were delivered, including the oil for heating.

Good evening,

If it turns out to be a lighthouse, just out of the photo shot,  then the rock could contain the jetty by which supplies were delivered, including the oil for heating.

Isn't that what I inferred in my post?

You need to read the replys SB.

I've been looking further afield.

With Caz's previous coastal pic being in Jersey, I've been map-hopping, and found this, not far from Greve de Lecq

Can't really tell what view they would have had though

No, scrap that - similar, but not near enough.
Oh dear

I was about to say I've been there and it would be something like this -

Does look really close though, so a good shout to remind us not just to focus on the UK

A slightly earlier view than you found, just because!  http://past-to-present.com/G14587
