The Temple of Hera Lacinia rises on the highest rocky spur of the Hill of the Temples, with the façade facing east.
The temple, like others in the city, is of Doric order and can be dated to around 450-440 BC.
The structure has an imposing basement of four steps. Of the thirty-four columns still standing, as many as sixteen columns still have their capital.
Those on the north side also support the architrave with part of the decorative frieze.
Inside, the walls still show signs of the terrible fire that destroyed the temple in 406 BC, during the Carthaginian conquest of the city.
