During Earth Hour on Saturday, administrative and public houses, archaeological sites and a large number of homes all through Greece turned off their lights as a part of a worldwide initiative to emphasize the risk of climatic change.

The majority of Greeks joined the rest of the world in the global event started by the World Wildlife Fund (WWF) to dim nonessential lights from 8:30 p.m. to 9:30 p.m.

Around 4,000 cities and towns in 88 countries and regions joined the glabal event.

In Athens, the city centre and surrounding localities, in addition to its nearby areas, plunged into near darkness as many of the lights were switched off beside roads and public squares, historic and cultural monuments including the Parthenon, the Temple of Poseidon at Sounion, the Ancient Agora, as well as the Parliament building, military divisions, sports grounds, municipal buildings, Lycabettus Hill, parts of the Athens International Airport, and billboards along with outside lighting at the Athens Metro.

The Athens municipality also staged a music concert at Pnyx Hill across from the Acropolis, while various musical events, without lights and "unplugged", were staged in various other parts of the city.

A similar turnout happened in Thessaloniki and other nations and townships all through the country.

The Public Power Corp. (PPC) also took part in the effort, turning off outside lighting and lights within its different facilities.

According to reports, New Zealand turned one of the first nations to turn off the power. Auckland's Sky Tower, the Beehive (parliament building) in Wellington and Christchurch's Cathedral Square were a few of the country's familiar sights taking part.
