Just found this little piece of information on Wiki..
In 1926 the erosion of the sand dunes near the Serpentine, brought the sides of several large houses down. The River Alt at Formby and Hightown were a major cause to the erosion of the banks of the River Mersey at Crosby.
The sea moving ever closer, brought about the total demolition of the residences. Over the years since the erosion the site has become a promenade for walkers, with a car park with a view!
(So this would mean, demolished houses at Blundellsands would be to the left of coastguard station at Hall Road, and the Bootle wartime rubble to the right)
Bootle wartime rubble still remaining, mainly alongside new coastal path, will try and get a few pictures!
Another bit of info about Fort Crosby!
Hightown Beach is the site of a former wartime military base known as fort Crosby.
The fort was situated midway between Hightown and Hall Road and housed a number of Italian and German POWs during WW2.
Following its decommission at the end of the war a small Cinema Screen within the complex was reputedly used by local residents for a number of years until the camp was finally demolished in the mid - 1960s.
Remains of many of the buildings, pathways and fences can still be seen today!!
Never really noticed before, must take time more time to look
