What's so great about this picture

As part of my end of month internet splurge (I try and somewhat moderate my internet usage during the month, so at the end of the month whatever's left gets blown in an outrageous fashion) I've been uploading a bunch of photos up to my flickr account. This has led to a surge in people looking at my photos, which is kind of to be expected since flickr shows people random recently uploaded photos, and I have it set up so that a message goes up on facebook when I upload photos.

Looking at the stats flickr provides though shows one anomaly, this picture:
Yesterday it got 237 views. This blows away the next best photo which currently sits at around 85 views and is of what I would consider to be a much more popular subject. In fact this photo beats the next 4 photos combined when it comes to views.

So I have to wonder, what's so great about this picture? It's a fire place with a statue above it in Cardiff Castle. It's not significantly better than any of my other pictures, nor is it significantly noteworthy in terms of content or style.

Any ideas readers?
