We spent a lovely Saturday afternoon wandering north from Crosby Coastguard station, an area I've coined the 'Brick Beach'. The coastline here consists entirely of rubble: bricks, plinths, granite pillars, doorsteps etc.
I can only imagine that this area served as a dumping ground after the Blitz, with the secondary purpose of slowing coastal erosion. Can anyone confirm this? I've been unable to find anything concrete (ha!) on the web, and would love to read any first-hand accounts or anecdotes. I'm moved by the sight of so much human endeavour, laid waste by warfare and now pounded by the sea back into sand.

I'm a bit rusty on the geography of that area so i don't know if it's relevant but certainly at Hightown some buildings were just abandoned to coastal erosion and this page mentions builders' rubble being chucked in to try and control the Alt at its mouth.

Thanks geoffrey - that page seems to be talking about the dumping of rubble to backfill the sea wall. Here's a Google Maps link (http://maps.google.com/?ie=UTF8&ll=53.497741,-3.059075&spn=0.002278,0.005021&t=h&z=18&om=0)to the area I'm talking about. On the satellite view you can see the red tinge of the bricks. I haven't walked that far yet, but it does appear to stretch as far as the mouth of the Alt. There's clear evidence of erosion, since the rubble forms a cliff in places. But where did it all come from? I'd love to know if anyone can confirm that this is from the Blitz

It was used to dump materials from buildings being demolished.You can see
large pieces of sandstone which look as if they might be parts of some old churches. I think the idea was to try to stop the erosion by the tide.
The actual Burbo Bank is the large sandbank which appears off shore at low
water where Liverpool`s old fishermen would clean the keels of their boats.
I used to there with my brother and his boat.you would be surprised at the amount of coal and broken crockery you could find. We always brought the coal home for the fire.
