  The issue of the orientation of Greek Temples has been the subject of several
debates since the end of the 19 century. In fact, although a general tendency
to orientation within the arc of the rising sun is undeniable, specific
patterns and true meaning remain obscure. With the aim of shedding light on
this problem we present here a new complete, high precision survey of the
temples of Akragas, the so called Valley of the Temples UNESCO site. Our
results include a important temple which was essentially yet unpublished, and
most of all show that very different reasons influenced the orientation
choices, some symbolical, but others by far more practical, besides the general
rule of orienting to the rising sun. In particular, the existence of temples
orientated in accordance with the towns grid, as well as to the cardinal points
irrespectively from the sun's declination associated to true east at the uneven
horizon, is evidenced. Finally, for two temples having anomalous orientations a
stellar and a lunar proposal are made respectively
