It is another brick, gothick castle built in early 14 century.
Are these Watermarks or Graffiti on the Canon and right wall? Otherwise a very clean post.
Yes,it is a watermark.
@aperture8 , Thanks for the info. The watermark IMHO distracts and blemishes an otherwise fine capture and post. A Small Well placed WM at either side (bottom) would work much better and not devalue your image. Just ONE man's Opinion. Thanks for sharing and have a great day.
