Mount Pentelicus or Pentelikon (Greek: Πεντέλη, Πεντελικόν or Πεντελικό Όρος) is a mountain in Attica, Greece, situated northeast of Athens and southwest of Marathon.

The roadway used to transport marble blocks from the quarry to the Acropolis in antiquity is a continual downhill, and follows the natural lay of the land.

It has been researched and fully documented by the chief Acropolis restoration architect, Professor Manolis Korres, in his award-winning book From Pentelicon to the Parthenon.

Pentelic marble is white with a uniform, faint yellow tint, which makes it shine with a golden hue under sunlight.

[6] A fire in early July 1995 consumed much of the mountain forest, and the eastern half became residential districts of the Athens area.

[citation needed] The blaze burnt tens of hectares and lasted through the late afternoon to the late-night hours, and was seen as far as neighborhood streets and broader Athens.

This time the wildfire was larger and more destructive, with flames towering as high as 50 to 60 m, and almost blocking any view of the sky, along with an attendant smoke.

During the country's worst ever fire, which broke the 1950s record on August 26, 2007, flames sparked by arson ravaged the forests of the remainder of the area around Mount Pentelicus and burnt pine, spruce and fir trees, lasting for several days; this was not the same blaze that had arrived from Keratea and Markopoulo to the south.
