The Hellenistic temple is dated to the 3rd century BC. It was enlarged in the 1st century BC and provided with a propylon.
The structures visible today date from this period. The temenos of the temple were built with rectangular masonry.

(The Temenos describes the delimited district of a (originally Greek) sanctuary. The perimeter itself, called Peribolos, is usually formed by walls, often overman-high, or porticoes, sometimes by fences. The entrance to the sanctuary is usually through a gate, a propylon, architecturally set.)
