The temple of Segesta, solemnly placed on a hill at the foot of Mount Barbaro, is certainly among the most exciting examples of Greek architecture. Completely isolated from the urban world, its white columns stand out among the green of the landscape,.
Its construction dates back to the late fifth century BC, during the alliance with Athens. There are a total of 36 columns, not partly scalanated to avoid possible optical illusions (a technique also used in the Parthenon in Athens).

There was much debate about the function of the temple: the prevailing view is that the building was deliberately unburied, in order to let know of a pre-existing local place of worship, where the celebration took place outdoors.

Dug on the walls of Mount Barbaro, scenically place to the north, with a beautiful view of the sea, surrounded by green fields, the greek theater of Segesta is a further example of the importance that the city claimed in its past. Probably changed during the Roman period, the theater now has about 4,000 seats, divided over 20 orders of rows.

The landmark, preserved only in part, was equipped with underground passages that allowed the actors to suddenly appear during the scenes. The acoustic resonance is still well maintained, so the theater can still be used for various comedies and tragedies.
