In The New Mutants, what is the name of the facility where the young mutants are held?

The young mutants in The New Mutants are held at Milbury Hospital.

The facility appears to be a psychiatric hospital where five teenagers receive treatment after dangerous incidents connected to their abilities. Dr. Cecilia Reyes supervises them and tells them that they must understand and control their powers before they can leave.

As the story develops, the teenagers discover that the hospital is not simply a medical institution. Its isolation, surveillance, and hidden purpose are tied to experiments involving young mutants. The setting gives the film its horror-influenced atmosphere and keeps the characters physically separated from the wider X-Men world.

Milbury Hospital is sometimes confused with Xavier’s School for Gifted Youngsters, but the film deliberately uses a different institution. The characters are not being trained by Charles Xavier; they are being confined and studied.
