Inspiration point (IP)

Last week, I watched a documentary about Berlin's Hansa Studios, which stood in the shadow of The Wall, when I used to live there. Some seminal albums were recorded there including Bowie's Low and Heroes, and Iggy's Lust for Life. Since the wall came down and reunification, people from Marillion's Fish to U2's Bono have said the place no longer has its aura.
So that's your IP, write about a place that's lost its power, be that just for you, or for everyone. It could be your old school, it could be a pub that's long gone, it could be a ruined castle on a long-forgotten border. Good luck!
