These are two beautiful, very old, Banyan tress.
So now with some assistance from my friend Mr. Wikipedia; "the aerial roots grow down and around the stem of the host, their growth accelerating once the ground has been reached.
Over time, the roots coalesce to form a pseudotrunk, which may give the appearance that it is strangling the host."
"The original support tree can sometimes die, so that the banyan becomes a "columnar tree" with a hollow central core".
Especially on an old tree like this.
They look as if they should be throwing apples at Dorothy.
Ordinary, that is, until you get close. And the sun goes down........
