Drone footage released by researchers shows the city centre is marked by a circular structure on a hillside terrace, with remains of stone and mud buildings constructed some 600 metres (1,970 feet) above sea level.

The urban centre, named Peñico, is located in the northern Barranca province and was founded between 1,800 and 1,500 BC. It is close to where the Caral civilization, the oldest in the Americas, developed 5,000 years ago.

Like ghosts from the past, sunken villages at the bottom of water reservoirs are not meant to be seen. But the ruins of Kallio in the mountains of central Greece are becoming very much visible — and they have a warning to deliver.

As an unprecedented drought induced by climate change rampaged across much of southern Europe this past summer, reserves at the artificial Lake Mornos — the biggest of the four reservoirs supplying drinking water to Greece's capital, Athens — hit their lowest in 16 years.

The receding waters exposed what was left of Kallio, a village submerged in the late 1970s to create the reservoir some 200 kilometres from Athens.

Researchers have long debated what became of the people sometimes called Ancestral Puebloans, who lived in the elaborate Mesa Verde cliff dwellings and other communities across the Four Corners region, where the states of Arizona, Colorado, New Mexico and Utah meet.

Archaeologists believe the Ancestral Puebloans were a flourishing population of about 30,000 in 1200, but by 1280 they were gone, driven off by a devastating drought, social turbulence and warfare.

Because they left no written record, their paths are not known with certainty.
Many archaeologists and present-day Pueblo Indians believe the Ancestral Puebloans moved to villages across New Mexico and Arizona, and that their descendants live there today.

Archeologists in Turkiye discovered an ancient fortress half-buried at the bottom of the country’s largest lake, where the alkaline waters have kept the structure well-preserved for approximately 3,000 years.

The lost fortress is thought to have been built millennia ago on the shores of Lake Van, back when the Urartu civilization populated that area of the Armenian Highlands.
Water levels have risen by several hundred metres since that time, and the fortress is believed to have been abandoned as a result.

'The communities that built the monumental megalithic structures of Göbekli Tepe lived during one of the most momentous transitions in human history, one which took us from hunter-gatherer lifeways to the first farming communities. The monumental buildings at Göbekli Tepe demonstrate the creative human genius of these early (Pre-Pottery Neolithic) societies.' (UNESCO)

Only a small portion of the site has been excavated properly, but the most important building appears to be a massive public bath.
Houses had tiled bathrooms and their own cylindrical brick wells, sometimes raised to the second floor to allow for a flush system.
