The answers

Remember the competition that I post earlier,well its kinda dissapointing cos no one got the answer right.Monument of love
This is the code given:

NPOW NFOS PGMP WFST

The answer is:

1) Rearrange it into a square

N N P W
P F G F
O O M S
W S P T

2) replace the Alphabets with the Alphabets before them

M M O V
O E F E
N N L R
V T O S

3)Now u can see that its consisted of 4 words which are:

MONVMENT OF LOVERS

As u can see that the word,"MONUMENT" was spelled wrongly. Its supposed to be a V instead of W so that the word could be spelled correctly. That was supposed to be a hint for breaking the 2nd cipher that I used.

The answer is the Taj Mahal.
