I have started a new group. Its object is to  post pictures of pairs of towers - could be two twinned towers that are part of the same building, as is the case for many churches,

- or.... could be a juxtaposition of two towers to contrast their appearances or functions or both.

Remember that not all twins are identical!

See:  http://www.ipernity.com/group/32461 for some of my ideas................but feel free to post anything that  fits my description of the theme!
