Spiral staircase in Dunstanburgh Castle

This is looking down the spiral staircase inside one of the towers at Dunstanburgh Castle, near Craster, Northumberland, from August 2013. It's a classic type of shot that I've seen lots in books and online, but it was still great to be able to take it myself. I love the patterns and textures made by the shafts of light on the steps and handrail.

I converted to monochrome and increased exposure slightly.
