Even since antiquity, Mt. Pendeli (ancient names Pentele, Pentelikon) (Elevation 1,109 metres) has been famous for its marble which was used for the construction of the Acropolis and other buildings of ancient Athens.
Pentelic marble, originating on Mt. Pentelikon north of Athens, was first used on a large scale for the construction the "Older Parthenon," a structure on the site of the current Parthenon that was destroyed before completion by the Persians in 480 BC.
Pentelic marble is flawless white with a uniform, faint yellow tint (caused by a trace of iron oxide), which makes it shine with a golden hue under sunlight. The ancient quarry is protected by law and used exclusively to obtain material for the Acropolis Restoration Project.
Ther are many Quarrries on the mountain but from scientific analysis it now seems three supplied the marble for the Elgin Marbles. Eventually the quarry that suplied the marble for the Parthenon may be identied.
