Achalm and Reutlingen
Two of the more familiar landmarks of Reutlingen are the Tubinger Tor (top) and the Gartentor (below).  I have heard the latter called the Reutlinger Tor by my family, but I have not confirmed that anybody else called it such.  The photos on the left are from 1978, while the ones on the right from 2007.  The Tubinger Tor's topography had changed dramatically with the construction of a walkway over the busy road nearby, and it was impossible to get an identical angle.  However, I was able to do so for the Gartentor.
