Through the doorway!

I took this image this morning, it was a dull damp day, so I thought monochrome rendering was suitable.  This is Sketrick Castle and through the doorway you can see the short causeway that connects Sketrick Island to the mainland.  The site dates back to the twelfth century.

This is also the first time I have used a 35mm lens in a very long time!  I see the site metrics show it as 50mm, this is incorrect.
