st stephen's church, hampstead, , london

Thanks for posting all these photos of St Stephen's, Stiffleaf. I used to stay in Belsize Park on my annual trips to London, and often walked by the church when it was closed up and had scaffolding around it. Always wanted to see the inside, haven't had the chance yet. Was it open for an event when you went in? Or is it just open for anyone to take a look?
