Eerie photos reveal abandoned Oklahoma Tuberculosis sanatorium which treated patients in the early 1900s in ruins

The Eastern Oklahoma Tuberculosis Sanatorium was built in 1921 to care for patients with the disease

Advanced treatment and a declining need for the sanatorium closed the facility in 1975

Photographer Dax Ward travels the world searching for beauty in decaying structures and captured the building in a series of eerie photos

Brick and rubble line the floors and plants have grown in the old rooms 

The sanatorium is believed to be haunted by the spirits of the children who died while being treated  

Eerie images show a sanatorium in ruins that's said to be haunted by the those who died after being treated there in the early 1900s

The Eastern Oklahoma Tuberculosis Sanatorium was built in 1921 to care for adults and children suffering from Tuberculosis

American photographer Dax Ward captured the withering historic building as he travels around the world searching for the beauty in decaying structures

Advanced treatment and a declining need for the sanatorium closed the facility in 1975

Now, the hospital that appears in tact from the outside is broken and dilapidated from the inside

Brick and rubble line the abandoned hallways and bathrooms of the building

The photographer said he'd been wanting to document an old TB sanatorium for a long time and  jumped at the chance to shoot this one

Plants have begun to grow in what once were children's bedrooms

The photographer said the floor was covered with brick and debris making for treacherous stair climbing

Ward snuck in through an open window with his father. All the other windows and doors were barred shut

The Harper building was the children's section of the hospital where it's rumored many died and their spirits still haunt the facility

The building is still owned by the Oklahoma Government and the Harper building where the children lived is in danger of being demolished
