  The Hittite city Sarissa was founded in the 16th century BC and has been
systematically constructed. The city gates and the bigger public buildings were
arranged at about 45{\deg} relative to the cardinal directions. However, one of
the temples features a remarkable deviation from this general orientation. The
following analysis shows that both, the general orientation of the public
buildings and the deviation of one of the temples are related to astronomical
observations, particularly to the course of the sun, and maybe also to some
special points of the course of the Venus.
