Map of Summer Palace by blue_sky04
The palace is impressive!!! It's huge and beautiful. I even heard a rumor that the lake and the hill are man-made. I have not done any reseach/reading to prove the rumor. If it is true, this fact adds one more reason to call this place impressive.
I hope the maps can be helpful for you to get the idea about the Summer Palace and you can use them when visiting the palace.
