Located in the heart of Los Angeles' famed film district, the museum houses the world's largest collection of serial murder artefacts.
Founders J. D. Healy and Cathee Schultz started the museum to share their own collections.
They say they wanted people to be able to revel in all things deathly.
"The Museum of Death incorporates everything from serial killer artwork and letters, execution videos, mortician devices, famous crime scene photographs - anything that you can think of about death, we have it here," he said.
The museum's 45-minute walk through begins with the "Serial Killer Archives" section.
Here, newspaper articles, letters and artwork are displayed, belonging to killers such as John Gacy - the so-called Killer Clown who was convicted of the sexual assault and murder of some 33 teenage boys and men; Richard Ramirez , dubbed the ' Night Stalker' ; and David Berkowitz, the notorious Son of Sam who claimed a demon dog ordered him to kill.
Next is the "Execution Room", where an electric chair sits next to a real severed head.
It belonged to Henri Desire Landru, a French serial killer who put ads in the 'lonely hearts' sections of Paris newspapers to attract unknowing victims.
He was beheaded by guillotine in 1922.
Also in the "Execution Room" are articles on Oklahoma bomber Timothy McVeigh and photos of executed killer Ted Bundy.
"When you come to the Museum of Death you definitely can't be squeamish because we like to call them "falling down ovations" when the boys - and it's usually boys or men - fall over and actually pass out," says Shultz.
The "Mortician & Funeral Room" features items used in funeral homes over the years including caskets and embalming tools.
The so-called "Carnage Corridor" includes real human skulls on display next to several animal skulls and skeletons.
In the "California Death Room", Charles Manson takes up an entire alcove.
In 1969, actress Sharon Tate and four other people were found brutally slain at Tate's Los Angeles home; cult leader Charles Manson and a group of his followers were later convicted of the crime.
As visitors turn a corner, there's a showcase of newspaper articles on O.J, Simpson who's currently incarcerated in Nevada Prison.
In 1995, he was acquitted of the murder of his ex-wife Nicole Brown Simpson and Ronald Goldman.
Also in the room is the story of the so-called 'Black Dahlia' murder.
The nickname was given to Elizabeth Short, who died in a gruesome murder in 1947 Los Angeles.
The Museum of Death is just one part of Hollywood's countless tourist destinations.
According to President and CEO of the Hollywood Chamber of Commerce, Leron Gubler, they've been working hard to show tourists the district isn't all glitter and glamour.
"Twenty-two years ago, Hollywood was not what people envisioned," he said.
"They saw the movies and thought that Hollywood would be glitz and glamour and it wasn't. So, we've been working very hard to turn Hollywood around. And over that time more than four billion dollars has been poured into Hollywood and another four billion dollars is in the pipeline, so a lot's happening to restore that glitz and glamour and the sheen to Hollywood."
According to Gubler, more than 12 million tourists visit Hollywood every year.
There's no age limit to gain entry to the Museum of Death, but management say it's definitely for mature audiences.
And if anyone falls victim to the museum's "falling down ovations", there are smelling salts close by.
