I have been successful in creating two new objects (thanks to forum members) for your town square or to use as a roadside monument. They are a Cross on a pedestal and a shrine to the Madonna (using a graphic of an actual 16th century French painting). Both objects Fade when a unit is next to them and the Cross will block LOS as it is fairly tall. Neither object takes damage, after all they are protected by divine intervention!
Instructions on how to install these objects is included in a Read Me file in the Zip file.
Here is a image of the objects. The download link is at the bottom of the post.
