Taj mahal is one of the best tourist sites i have ever been to..... It is a well know fact, that it is termed as the symbol of love, i would add to that" it is also the symbol of hard work"..... It is 22years of hard work by some thousands of people, which made this architectural wonder " Taj mahal " possible.
Well, My favorite is Switzerland !! I hope I will go there in future. Its the best place in the world i think.
As for me i perfect place is wherever I can get relaxed and It has flowers and trees. Hawaii could be a good option.
