How on earth do you get to this mound?

I noticed there's a "door" on the ground, but can't find an entrance. I've tried interacting with everything I can think of in the Graveyard / Church and naddah.

Any one able to shed some light on this one?

*EDIT* Asked and answered.

Secret door in the church ftw
