Conway Hall

This building is like a little Harry Potter secret in London. You have to know it's there - tucked away in the corner of Red Lion Square by the little alley.  They often have piano auctions here but mainly it's an ethical society, the only remaining one in the UK, and is thought to be the oldest surviving freethought organisation in the world.

It's a bit of a rubbish picture on an iPhone as I was rushing to the ex-Econ christmas drinks, but I had forgotten about it being there, and loved it all lit up at night.
