A few yards further along from the Spa is this new-to-me lifeboat station which with its white curves and windows pays a passing homage to the art deco-ish Spa. However a few yards further brings us to this piece that seems to be a relic of Rommel's Atlantikwall, I believe it's something to do with the sewage out fall pipe they were putting in a while back. It does make for a fine vantage point if you clamber up the top of it, and from there, of course, you can't see it; so win-win.
If you're wondering why the RNLI needed a new station it's because the old one (below) was a) not even close to the beach and b) it was across the road and traffic had to be held up and so on whenever there was a call out.
