I was doing research on places I could find fig trees on a trip that I am planning to Turkey and I found something interesting.


In the garden of the Topkapi Palace in Istanbul there are fig trees growing inside other types of trees!

Update:
I found a partial reason as why the fig trees in the picture are growing inside the trunks of other trees.

from Wikipedia:
Many of the trees in the Topkapi Palace are remarkable since most of them fell victim to a fungus that completely hollowed the trunk out over the centuries, even though the trees still survive until today and are standing. In other cases, two trees of a different kind have grown and fused together, such as a fig tree that grew in the hollow of a tree and effectively fused together. This phenomenon can be seen in the Second Courtyard.
