The tallest trees in the world are the Evergreen Redwoods (Sequoia sempervirens). They grow on the west coast of the United States, mostly in northern California (but also partly in southern Oregon). Officially the tallest tree in the world is the Hyperion sequoia, which measures an impressive 115.85 meters in height Hyperion grows in Redwood National Park, as do the second and third tallest trees in the world, Helios and Icarus, but the exact location of these trees is unknown for fear of being damaged by tourists and vandals. examined Hyperion, it is about 700-800 years old, which is not an impressive age for evergreen redwoods – these trees can live for up to 2 millennia. They are also undoubtedly record holders among trees – no other species reaches a height of more than 100 meters. if you compare Hyperion to a building, it would turn out that the 11-story Big Ben in London is 20 meters away from it lower thrust.
