Atmospheric horror films

[Swamp Thing]

I really love arty horror and movies that ooze atmosphere. I'm a sucker for period pieces the most. What are some of the most atmospheric horror movies you have seen?

I think stuff like:

Dracula (1979)
Candyman (1992)
The Others (2001)
Graveyard Shift (1990)
The Company of Wolves (1984)

DAGON
PAN'S LABYRINTH
ABSENTIA

[Silverlady]

Cat People        1942
The Haunting    1963

I Walked With a Zombie - 1943

I don't think it's possible to lay on atmosphere any thicker than this.

.WHITE ZOMBIE (1932)-It's like a very Grimm fairy tale come to life...very sparse dialouge-coulda been a silent film.

.The OLD DARK HOUSE (1932)-No musical soundtrack,but with all the thunder and wind...it doesnt need any!

Carnival of Souls (1962) I think this would be right up your alley. Creepy old school movie thats available on youtube
[For a more recent one I was impressed by Ti West's House of the Devil. I felt he managed to effectively capture that classic horror atmosphere and slow pace of movies from the past.
Other noteworthy mentions would by The Changeling (1980) Messiah of Evil (1973) and the first two Omen films.

Not a period piece, at least not when it was first filmed, and not particularly scary, but 1944's "The Uninvited" w/ Ray Milland, Ruth Hussey, and Donald Crisp, which is regarded as being one of the best horror films ever made, because it is chuck full of atmosphere. And people have already mentioned a couple of producer Val Lewton's films. Here are some more.

Bedlam
Isle of the Dead
The Body Snatcher
The 7th Victim
The Leopard Man

And what he could do with horror, he could also do with westerns. "Apache Drums."

the first two Omen films.

first one, definitely. the bunch of creepy incidents surrounding the film suggest there was probably just as much of an 'atmosphere' off camera as well

Omen pt2...not so much. (imo)

it's not really a horror movie, but SE7EN has wonderful atmosphere.

Love that movie!  CAT PEOPLE (1942), same director, also heavy atmosphere.

NIGHT OF THE LIVING DEAD (original)
THE DEVIL'S BACKBONE & PAN'S LABYRINTH
THE SHINING
VAMPYR (1932)  is pretty much nothing but atmosphere. (And it's one of Dreyer's more accessible movies....)

Who Can Kill A Child
Carnival Of Souls (original)
Night Tide
Dead And Buried
Let's Scare Jessica To Death

[Chainsawmidget]

I really enjoy Daughters of Darkness. 

It's questionable whether you can call it a horror movie or not, but The Changeling is also really good.

A lot of John Carpenter's films, particularly:

The Thing
Halloween
The Fog

EDIT: Also, Suspiria.

Ahhh...The Fog! How could I miss that one? I think pretty much any Aregento film from the 70s/ early 80s qualifies as well. Cronenberg's 70s era stuff has a real seedy quality to it. Deathdream has a nice vibe to it too.
