As the building of the new sports arena advanced, its roots were damaged during excavation.
Developers well known care for nature.
Stadium builders had to remove the impressive poplar because it endangered the safety of work and bystanders.
This ten meters high and over 21 tonnes section of the old poplar tree was brought to the Botanical Garden.
After being treated and conserved, the trunk is expected to hold at least three decades, for visitors to admire it.
