Bells and bees

This afternoon, I spent a happy few hours cleaning a belfry. It's a very tiny tower, only about 3 or 4 square metres. There are four floors including the ground floor. I only managed to clean the ringing room (first floor) today, and a little bit of tidy up of the clock chamber (2nd floor). It was really quire filthy. I feel like I've vacuum cleaned away hundreds of years of cobwebs, sandstone dust and bees...

Most of the mess happened to be thousands upon thousands of dead bees. Apparently, some years they swarm into the top of the tower, live there for a bit then die during the winter. I'm not looking forward doing any maintenance in the bell chamber (top floor) during the summer.

So, now we have a belfry that people can go in without overalls. So, what's the next step? Ringable bells?
