(SOMEWHERE) You really shouldn't go

I have chosen to take a photograph for "somewhere you really shouldn't go" because i have a great place in mind already of where to take the pictures. In lancaster there is an arch way with a door that is meant to be blocked off ....but dun dun duuuun! Its OPEN! 

Behind this door there is a small area of shrubs and weeds but there is a circle where the shrubs and weeds have just stopped growing and in the center of this circle there is a stone/shrine where people actually come from all across england to worship the witches that were hung and buried there!

I want to take a photograph of this place and try to make it look spooky! I will then edit it also to give it some more effects.
