Watson’s Hotel, later called the Esplanade Building, was built between 1867 and 1869. It is the world’s oldest cast iron building. For years it looked like it would fall down at the slightest touch. Something is happening to it now, behind high barriers. I can see a scaffolding above the blue metal sheets. I hope it is repairs and renovation rather than demolition. It’s been a Grade II heritage structure for decades, but that did not apparently force anyone to keep repairing it.
