Gunung Padang
A hill in West Java is terraced and covered in columns of volcanic rock, and a 2023 paper argued the structure inside it was begun 25,000 years ago, which would make it the oldest built thing on earth. The journal retracted the paper in March 2024 because the radiocarbon dates came from soil with nothing man-made in it. All of the authors disagreed with the retraction, and the digging and the argument both continue.
Field Guide Entry
The site
Gunung Padang is a hill above the village of Karyamukti in Cianjur, its upper slopes built into five terraces and strewn with andesite columns, the hexagonal rock that forms when lava cools. Local people have used and known the site for a long time, and Dutch colonial officials recorded it early in the twentieth century. The visible terracing is generally read as a megalithic site of the last few thousand years.
The claim
A team led by the geologist Danny Hilman Natawidjaja used ground penetrating radar, seismic tomography, and cores drilled into the hill to argue that the terraces sit on top of engineered layers going down tens of meters, and dated material from those layers to as early as 25,000 years ago. The paper ran in Archaeological Prospection in October 2023 and drew international coverage of a pyramid older than agriculture.
The retraction
Archaeologists objected on a specific point rather than a general one. The radiocarbon dates were taken from soil samples that contained no artifacts, no charcoal from hearths, and no features that could be shown to be man-made, which means they date the ground, not anybody's work in it.
In March 2024 the journal's editors-in-chief, Eileen Ernenwein and Gregory Tsokas, retracted the paper with the publisher. The retraction notice states the material could not be reliably interpreted as human-made. All of the authors disagreed with the decision.
What is in dispute
Nobody disputes that Gunung Padang is a real archaeological site with terracing and worked stone. What is disputed is everything below that: whether the layers the radar found are built or geological, and whether anything on the hill is older than the megalithic phase. A retracted paper is not a refutation of a hill, and the hill has not produced the evidence the claim needs.
Visiting Information
Open daily from about 8am to 4:30pm with entry around 35,000 rupiah, and local guides wait at the bottom for a small fee, which is worth taking because nothing on the site is labeled in much detail.
Getting to the top means climbing the old stone stairway, which is steep, uneven, and long, or the gentler newer path to the side. Bring water; there is little shade on the terraces and the stone holds heat.
The road in from Cianjur is narrow and slow, and a driver for the day is the usual arrangement from Bandung or Bogor. Weekends bring domestic visitors in numbers, and weekday mornings are close to empty.

Bada Valley Megaliths
Scattered across a remote Sulawesi highland valley, more than 400 carved stone figures, some over four meters tall, were made by a culture that left no name, no writing, and no agreed-upon date behind.
Bosnian Pyramid of the Sun and Ravne Tunnels
Semir Osmanagic announced in 2005 that the hill above Visoko is a pyramid tens of thousands of years old, and started digging the following April. In December 2006 the European Association of Archaeologists published an open letter calling the project a cruel hoax with no place in genuine science. The digging did not stop, the tunnels are ticketed, and the town gets the visitors.
Actun Tunichil Muknal
Fourteen sets of human remains lie in the upper chamber where they were left more than a thousand years ago, some of them children. Pots sit among them with holes punched through the base so nobody could use them again. Cameras have been banned since 2012, when a visitor dropped one onto a skull.
Ale's Stones
Fifty-nine boulders stand in the outline of a ship on a ridge above the Baltic, the largest weighing about five tonnes, hauled up a slope to a spot with no shelter and no water. Radiocarbon puts the setting at around 550 CE. An amateur astronomer has spent decades arguing it is thousands of years older and is a solar calendar, and no working archaeologist accepts it.
