The start of a horrifying journey.
Is this journey in a book/movie?
Lots of books and movies about this journey, some of them are gorier than others.
Are this place and the journey linked to a religion?
House of Slaves on Gorée: en.wikipedia.org/wiki/House_of_Slaves
Great hints, gum.
Anybody else want to take a stab at picking a place? If so, go for it. If nobody posts a new one by tomorrow night, I will.

MiG, I don’t know how you got this one. The only hint was the horrifying journey and the book/movie/gory part. You must have incredible picture searching skills or an incredible ability to think “sideways”!
I might have something to post later today.
Would have gotten it quicker 
But was on the road.
