Charming unknown tomb

On my latest visit to Humayan's tomb, I didn't enter by the usual route.  I walked around the outside walls instead. 
And that lead me to this place:  an unknown tomb from the 16th or 17th century.

"Charming" is the only description I can find of it.
I agree.

But again, it shows that if history doesn't care to remember you, it won't.
