Staircase
Not many other words can describe this staircase other than maybe "wow". I rediscovered this photo tonight, which I took on a short family holiday in Wales back in May 2014.
Penrhyn Castle, where I took this photo, is a magnificent stately home near Bangor operated by the +National Trust, containing a mix of design styles from many periods. Beautiful gardens and grounds too - well worth a few hours out of your day.
