Facts about the Acropolis you might not know

Mentalfloss recently put together twelve facts about the Acropolis in Athens, which was quite entertaining. You can read the whole thing here, but below are the highlights.

ITS HUMAN HISTORY IS NEOLITHIC.
Humans have inhabited the limestone slopes of what became the Acropolis for centuries; they were likely drawn to the water from its natural springs. There's evidence of habitation in the area dating back to the Neolithic period between 4000-3200 BCE, with both a house and a grave identified from around this era. A series of shafts have also been discovered, with several vessels found in their deep chasms. One theory is that the shafts were once wells, while another is that they were a site of ritual burial, since human bones were found among the objects buried within.

ITS FIRST STRUCTURES WERE BUILT FOR DEFENSIVE PURPOSES.
From its central position above Athens, the Acropolis is perfectly positioned for strategic military defense—and its major initial structures were in fact focused on preparing for war. The ancient Mycenaeans built its first defensive wall in the 13th century BCE (a structure so strong that fragments still survive today), which was the primary defense of the Acropolis for around eight centuries. Eventually the site would gain religious significance, with temples being added to the area.

A COLOSSAL ATHENA ONCE PRESIDED OVER THE ACROPOLIS.
The Acropolis is the most complete surviving ancient Greek monumental complex, which is remarkable considering the centuries of natural disasters, war, and reconstruction. Still, much of its ornamentation and art is now gone. One of these losses is a colossal statue of Athena once located inside the Parthenon. Known as Athena Parthenos, it stood almost 40 feet tall and was made from gold and ivory by the sculptor Phidias. Dressed in armor and covered in jewelry, it was an awe-inspiring spectacle that reaffirmed Athens's spiritual and economic power.
The statue disappeared in late antiquity, and was likely destroyed—but thanks to Roman replicas, we can still get an idea of what the Athena Parthenos looked like. To experience a facsimile of its full scale, however, you must travel to Nashville, Tennessee. There, in the 1980s, artist Alan LeQuire created a full-sized reconstruction of Athena Parthenos, now housed within the city's Parthenon replica.

BRINGING MARBLE TO THE ACROPOLIS WAS A MONUMENTAL TASK.
The marble that composes the Acropolis’s classical structures, including the Parthenon, is not local. It was quarried at Mount Pentelicus, located 10 miles to the northeast of Athens and famed for the uniformity of its white marble. It was hard labor to quarry the marble, with stonemasons using iron wedges and mallets to pound apart blocks along their fissures. From Mount Pentelicus, workers used a downhill road to move the marble on its long journey to Athens, where they still had to get the rocks up the steep slopes of the Acropolis.

THE WORLD’S OLDEST WEATHER STATION IS AT ITS BASE.
Located on the slopes of the Acropolis is what's considered the oldest weather station in the world. Known as the Tower of the Winds, the octagonal marble structure dates back 2000 years, and is likely to have once held a bronze wind vane above its sundial. Many historians also believe that it contained a water clock that was hydraulically powered with water flowing down the steep Acropolis hill, so that Athenians could tell the time even after dark. Lord Elgin, who brought many of the Parthenon's sculptures to London, wanted to bring this structure as well, but was denied. After a recent restoration, it opened to the public for the first time in nearly two centuries in 2016.

RESTORATION STARTED 40 YEARS AGO—AND IT'S STILL GOING.
A major restoration of the Acropolis started in 1975, under the new Committee for the Conservation of the Monuments on the Acropolis, which meticulously examined the state of the hilltop and began work to return it to its ancient condition. Marble from the exact mountain where the original stone was quarried is used for structural interventions, and conservators employ similar tools to those employed by ancient artisans. But since just one block can take over three months to repair, the project is still ongoing—and will hopefully stabilize the site for centuries to come.
