There seems to be a metal bars-esque barrier in the passage behind Clavicus Vile in Haemar's Shame/Haemar's Shrine. Is there a way to open it?

Go up to the door, directly to the right of the door is a chain on the wall. If you can't find it I'll post a SS when I get home.

Edit: If you zoom in on your SS you can see it, snip here. enter image description here

Took me a while to find it as well, and I did look for it, I didn't find it till I came back the second time.
