Magnificently preserved, this Doric style temple is from the 5C BC. The prevailing impression when you are there is of a fragile and inexplicable harmony. Perhaps it is due to the art of the architect, who endowed the horizontal lines with an imperceptible convex curve, and slightly inclined towards the interior the flutings of the corner columns. But never mind the construction secrets which will only interest fans of geometry: the result is right there, total equilibrium!
