It took me while to round asking the woman at the garage whether the inconspicuous clump of gorse in the field behind her whole filling station was where the 3 brothers were residing. She said that they were out on the moor, which apparantly meant yes. And then I had gorse and heather to wade through for about 200 yards in sandals. Ouch!
The stones lie looking a little like a dolmen/quoite, in that one of them caps the other two, but I suspect that this is not their original state. It kind of looks like they’ve been dumped unceremoniously in a field, though that may be to fool such fools as me. Going on the name I think of the 3 brothers N of Lancaster and so imagine them standing seperatly. The surrounding land and sea is not dissimilar to Morecambe Bay either. There is a ruined chapel nearby in the NE of the field.
