A research team in the Czech Republic unearthed a box-like wooden structure used in the building of an old well.

The tree-ring dating technique has revealed that the oak wood used to make it was cut around 7,275 years ago. This makes it the oldest known wooden structure in the world, scientists say.

According to the study published in the Journal of Archaeological Science, the researchers used the tree rings and the radiocarbon dating techniques to determine the structure's age.

The age of a tree can be determined based on the rings or the annual growth layers of the trunk and roots' stems. It can be calculated by dividing the trunk's diameter by the tree's growth factor according to its type, and then multiplying the obtained result with the trunk's circumference. The final result would be the tree's age. Experts may also use the Radiocarbon dating technique known as "carbon-14 dating", which uses the radioactive properties of radiocarbon.

In a report published on the Science Alert website, Archaeologist Jaroslav Peška of the Archaeological Centre Olomouc in the Czech Republic, and the study's senior author said: "According to our findings, based particularly on dendrochronological data, we can say that the tree trunks for the wood used were felled in the year 5255 BCE. Some side wooden planks seemed a little bit younger."

The researchers suggested that the trees were felled 7,244 to 7,261 years ago, and the smaller planks were used in repairing the well at some point.

The well was unearthed and discovered near the town of Ostrov in 2018 during construction on the motorway in the Czech Republic.

Ceramic fragments found inside the well dated the site to the early Neolithic, but no evidence of any settlement structures were found nearby, suggesting the well serviced several settlements at a bit of a distance away.

The discovered structure consisted of four oak poles, one at each corner, with flat planks between them. The well was roughly square, measuring 80 by 80 centimeters (2.62 feet). It stood 140 centimeters tall (4.6 feet), with a shaft that extended below ground level and into the groundwater.

Northern Ireland's Giant Causeway draws close to one million visitors a year but their habit of wedging tiny coins in cracks between the rocks -- to bring love or luck -- is damaging the world-famous wonder.

Now authorities are urging tourists to keep their coins in their pockets to preserve the spectacular landscape.

Some 40,000 columns mark the causeway, Northern Ireland's first UNESCO World Heritage Site.

Geologists say the natural phenomenon was created by an outpouring of basalt lava 60 million years ago.

Legend has it that the causeway was formed by Irish giant Finn McCool.

In recent decades, visitors have pushed thousands of coins into fissures in the rocks.

The gesture is "a token of love or luck", according to Cliff Henry, the causeway's nature engagement officer.

But the coins rapidly corrode and expand, causing the basalt to flake and leaving "unsightly" rust-colored streaks, Henry told AFP.

He pointed to streaks on a rock and gingerly prized out a US cent with a set of keys.

"We get a lot of euros and dollar cents. But coins from literally all over the world -- any currency you can think of, pretty much -- we have had it here," he said.

A report by the British Geological Survey in 2021 revealed that the coins were "doing some serious damage" and something had to be done about it, he noted.

Signs are now in place around the site appealing to tourists to "leave no trace".
"Once some visitors see other people have done it, they feel that they need to add to it," causeway tour guide Joan Kennedy told AFP.

She and her colleagues now gently but firmly tell tourists to desist.

At the exit from the causeway, a US couple said they were "distressed" to hear of the damage the metal caused.

"Our guide mentioned as we came up that people had been putting coins into the stones. It's really terrible to hear that," said Robert Lewis, a 75-year-old from Florida.

"It's kind of like damaging any kind of nature when you are doing something like that, putting something foreign into nature. It's not good," said his wife, Geri, 70.

As part of a £30,000 ($40,000) conservation project, stone masons recently removed as many coins as they could -- without causing further damage -- from 10 test sites around the causeway.

Henry said the trial was successful and is to be expanded across the causeway.

"If we can get all those coins removed to start with that will help the situation and hopefully no more coins will be put in," he said.

"If visitors see fewer coins in the stones and hear appeals to stop the damaging practice, the problem can maybe be solved.

"We know that visitors love and cherish the Giant's Causeway, and many form deep personal connections to it, so we want this natural wonder to remain special for future generations."
