With your back to the front gate, just go once (one step) past the corner and look up at the mausoleum...there's a gargoyle on top of it you will probably have a hard time seeing. Then go back past the gate to the corner and look on the top corner of the outer walls of the cemetary. There's a gargoyle up there.
Go to your right and go down that trail just once, one step. Look at the top of the tomb off to your right for another gargoyle.
I think that will help you.
