Trees are easily some of the longest-living organisms on the planet, and even the oldest ones, some of which have been around since long before most civilizations show no sign of passing on anytime soon. That's pretty amazing if you think about it. Check out some of the oldest trees in the world below.

Methuselah
At 4,841 years old, this ancient bristlecone pine is the oldest known non-clonal organism on Earth. Located in the White Mountains of California, in Inyo National Forest, Methuselah's exact location is kept a close secret in order to protect it from the public.
Sarv-e Abarqu
Sarv-e Abarqu, also called the “Zoroastrian Sarv,” is a cypress tree in Yazd province, Iran. The tree is estimated to be at least 4,000 years old and, having lived through the dawn of human civilization not far away, it is considered an Iranian national monument.
Llangernyw Yew
This incredible yew resides in a small churchyard of St. Dygain's Church in Llangernyw village, north Wales. About 4,000 years old, the Llangernyw Yew was planted sometime in the prehistoric Bronze Age — and it's still growing!
Patriarca da Floresta
This tree, an example of the species Cariniana legalis named Patriarca da Floresta in Brazil, is estimated to be about 3,000 years old, making it the oldest non-conifer in Brazil.
Olive Tree of Vouves
This ancient olive tree is located on the Greek island of Crete and is one of seven olive trees in the Mediterranean believed to be at least 2,000 to 3,000 years old. It still produces olives, and they are highly prized.
Jōmon Sugi
The tree dates to at least 2,000 years old, but some experts believe it could be older than 5,000 years old. Under that theory, it's possible that Jōmon Sugi is the oldest tree in the world — even older than Methuselah.
Chestnut Tree of One Hundred Horses
This tree, located on Mount Etna in Sicily, is the largest and oldest known chestnut tree in the world. Believed to be between 2,000 and 4,000 years old, the tree sits only 5 miles from Etna's crater.
General Sherman
Believed to be around 2,500 years old, General Sherman is the mightiest giant sequoia still standing. The volume of its trunk alone makes it the largest non-clonal tree by volume in the world, even though its largest branch broke off in 2006, smashing part of its enclosing fence and cratering the pavement of the surrounding walkway.

What’s amazing about this is that these are some of the oldest trees that we know about. In the heavily forested parts of the world which have never seen a saw blade or an ax, there could be trees which put these to shame with their age.

Some of these trees on this list could even be older than we think; testing their age could damage them, which is why many scientists aren’t very keen to do it. It’s crazy to think that while we were still pounding on rocks and working on inventing the wheel, some of these trees had already grown to towering heights.
