This toothed tower is in remembrance of an elephant-judge.
Story is that the Mughals used to let “the accused” into a field with an elephant. It is for the elephant to decide whether the accused is innocent or guilty. Stomping would mean guilty-of-charge and on some days it would let off. That tower with protruding teeth you see marks the grave of that elephant.
Glad to not be ruled by such idiots any more.
