Absolutely not.
It is an architectural briliance.
I have been there repeatedly as my college was nearby but never feel it is enough.
I again visited there 2 yrs back.
It is the best architectural marvel I have ever been to....Its marvellous, its glimpse confuses how can a manmade thing be so magnificent and beautiful
Tajmahal is not at all overrated. It is an wonderful architecture. I have visited it both at dawn and at dusk. Two are very different views. It has captivating power. I have read about its beauty in moonlit night. Although I didnot have that opportunity. Looking forward to it in the future.
India is a land of diversity from dessert to snowcaped mountain's, beaches, hill stations, traditional, ancient and modern mixture, but too outsider's it is only known as a tajmahal country!!
Read the history. If you look at a thing done by his king for his queen, you might think it is over rated. But not when you look the people who built it and as an architectural beauty for the age it was constructed in.
In my opinion if we compare it with ou few Temples marvel engineering then yes it is..!! Because we have lots of temples which have more marvel engineering than this...however every places have its own charming and beauty..!!
Happy travelling!!
