Huge sandy beach in the East Riding of Yorkshire. Clear blue sky day in September 2020 and lots of derelict WWII concrete still waiting for the invasion that never came.
A fine set., the expression "sands of time" comes to mind.
They do make great subjects; both a reminder of times past and the inspiration for brutalist architecture.
It certainly is brutalist Dave. Many decades ago I was putting together a panel of photographs for a local club and I titled mine 'Architecture of War' as I grew up in Lincolnshire surrounded by such examples. I would love though to visit the old examples on the coast in France near to the D Day beaches. I have seen the ones in the Channel Islands.
