The Taj Mahal

Hmm.

Not much to say that hasn't already been said. I'll defer to the great scholar Wikipedia on the subject:

Emperor Shah Jahan himself described the Taj in these words:

Should guilty seek asylum here,
Like one pardoned, he becomes free from sin.
Should a sinner make his way to this mansion,
All his past sins are to be washed away.
The sight of this mansion creates sorrowing sighs;
And the sun and the moon shed tears from their eyes.
In this world this edifice has been made;
To display thereby the creator's glory.
