Whether you believe in ghosts or not, you have to agree that some buildings possess an eerie atmosphere. Maybe they are haunted, maybe their history is filled with death and tragedy, or maybe these buildings just look creepy. The buildings listed here are among the world's most frightening. BOO!

01 of 10 Ennis House in Los Angeles, California Justin Sullivan / Getty Images Designed by Frank Lloyd Wright, the Ennis House is one of Hollywood's favorite creepy places. It's where Vincent Price held his creepy dinner party in the 1959 film House on Haunted Hill. The Ennis House also appeared in Ridley Scott's Blade Runner and in eerie TV shows like Buffy the Vampire Slayer and Twin Peaks. What makes the Ennis House so spooky? Maybe it's the pre-Columbian look of the textured concrete block. Or, maybe it's the years of weathering that put the the house on the National Trust's "Most Endangered" list.

02 of 10 Notre Dame Cathedral in Paris John Harper / Photolibrary / Getty Images Just about any medieval Gothic cathedral can seem scary, but a lavish cathedral like Notre Dame Cathedral in Paris can truly make you tremble. It's supposed to, with all those snarling gargoyles perched on rooftops and ledges.

Of all the Newport mansions, the brooding Breakers Mansion has the most compelling tale. Believers claim that the ghost of former owner Cornelius Vanderbilt wanders the lavish rooms. Or, maybe it's the spirit of architect Richard Morris Hunt, who was born on Halloween.

04 of 10 Lenin's Mausoleum in Moscow, Russia Jorge Láscar / Flickr / CC BY 2.0 Stark and inhuman, Russian constructivist architecture can seem scary enough. But go inside this red granite mausoleum and you get to see the corpse of Lenin. He looks a little waxy inside his glass case, but they say that Lenin's hands are faintly blue and horribly life-like.

05 of 10 Boldt Castle in the Thousand Islands, New York Kevin Spreekmeester/First Light Collection/Getty Images Boldt Castle is both romantic and haunting. Gilded Age multi-millionaire George Boldt ordered the castle built as a testimonial of his love for his wife, Louise. But Louise died, and the grand stone estate was abandoned for many years. Boldt Castle is restored now, but you can still hear the lovers' footsteps in the long, echoing corridors.

06 of 10 The Amityville Horror House in Amityville, New York Paul Hawthorne/Getty Images Cream-colored siding and traditional shutters make this Dutch Colonial Revival home appear cheery and comfortable. Don't be fooled. This house has a horrific history that includes grisly murders and claims of paranormal activity. The story became famous in Jay Anson's best-selling novel, The Amityville Horror.

07 of 10 Archbishop's Palace in Hradcany, Prague Tim Graham / Hulton Archive / Getty Images Welcome to Prague? The castle that appears so foreboding in the Tom Cruise film, Mission Impossible has towered over the river Vltava for a thousand years. It's a part of the Hradcany royal complex where Romanesque, Gothic, Renaissance, Baroque, and Rococo facades create startling juxtapositions. Moreover, the Archbishop's Palace is in Prague, home to Franz Kafka, the famous author of surreal, disturbing stories.

08 of 10 Houses in Celebration, Florida Jackie Craven Homes in the planned community Celebration, Florida are mostly neotraditional styles like Colonial Revival, Victorian, or Craftsman. They are attractive and, from a distance, they appear convincing. But look closely and you'll see details that will send a chill down your spine. Notice the dormer on this neotraditional house. Why, it's not a real dormer at all! The window is painted black, as frightening as Hitchcock's Bates Motel. One has to wonder who lives here?

09 of 10 The Berlin Holocaust Memorial in Germany Sean Gallup/Getty Images "Chilling" is the word visitors use to describe Peter Eisenman's Memorial to the Murdered Jews of Europe, the Berlin Holocaust Memorial. Even if you did not know the horrific history that inspired the structuralist memorial, you would sense it as you wandered the labyrinth of pathways between massive tomb-shaped stone slabs.
