The OP is referring to Black-Briar Manor in Riften. In the basemant is the Sacrament and on a bookshelf in Maven's bedroom is a Dibella Statue.
In Riftweald Manor there is also a Dibella Statue.
I don't think there's one in the Black-Briar Lodge in The Rift.
I've never seen more than one in one place.

I know the one at Deekus' camp respawns though.
Now wait a doggone minnit. I thought it'd been established that the OP was referring to the Lodge (note the Frost and Sibbi refs in a few posts), and since in my first post, I addressed the Manor, but got redirected to the Lodge... (*circus music plays in the background*).
So anyway, I used my handy-dandy console to rapidly investigate all 3 possible locations: the Manor in Riften, the Lodge east of Riften, and Mercer's house in Riften. None of them are exciting, but Mercer's has the most and best loot.
Dibella statue-wise: there's one in Riftweald, one in BB Manor, one in Broken Tower Redoubt, one in the Temple in Markarth, one in Haelga's Bunkhouse, one in Brinewater Grotto, one spawns with Velekh Sain's treasure, and the one at Hela's Folly (Deekus' camp). That's it, AFAIK. *shrugs* I just don't know why, in my mind's-eye, I see a room full of Dibella statues. Maybe she's trying to commune with me...
