I was going down Battersea Rise last night in the direction of Wandsworth, and stopped at the lights at the bottom of the hill. I looked right, and noticed a nice building with a placque reading ‘Temperance Billiard Hall’. Then I looked down, and noticed that the building was now a bar… 
Your go…
This is littered with lack of detail, but…
“Someone” on a “Who Do You think You Are” discovered that their grandfather had been a head teacher at a Board School and a leading light in the local temperance society and raised enough money to build a temperance hall. Now a Weatherspoons.
A “sea men’s mission hall” in Brittany that was now the local union headquarters for agricultural workers.
A pub in rural Kent / Sussex that’s a Chinese take away. Still with (modified) pub sign.
Within a couple of hundred metres of where I live is an ex Metropolitan Police station that’s now a Nepalese restaurant. Still says “Metropolitan Police” in the stone lintol over the door.
Only humans that notice the irony. The buildings just soldier on.
:unsure:
There hardly ironic are they?
its not a building, but how about this ? 
I thought he misread it to read…iconic.
