Library without lights !

Recently i have visited a library in Zinda Park, Naraynganj,Dhaka,Bangladesh.
The library was amazing.
It had no lighting facilities inside it.
It is so nicely designed that no lighting is required.
Hats off to the architect and thanks to those civil engineers who made it.
I am giving you a inner view of it.

If you want, you can go and visit the place.
