Unknown Structure - Capture Suggestions

[asnow]

I have no idea what this structure is. However, the texture in the stone and the shape of the windows really caught my attention. I not really happy with these pictures.

Any suggestions how I might have captured this better and what processing I should try. I would like to go back and try this again. Note: This may be after the snow is gone. After the weather we are expecting this week, there might not be much snow left.
