Update as of 2010. My initial photos were from a distance and in 2010 I attempted to visit the site. As it turned out, the site is off limits to visitors so I could not gain access. I did get a chance to walk around part of it for some additional photos.
These photos date from 2007 and 2010.
An ancient church, dated ca A.D. 900. Photos 2010.
This is Heinsheim Church near Ehrenberg.
