Warner Bros. has announced it will put the massive model of Hogwarts School of Witchcraft and Wizardry used in the Harry Potter films on public display for the first time.

The castle will be the final stop on WB's new Harry Potter Studio Tour, which also includes a look at sets like Diagon Alley, Hagrid's hut and the Gryffindor common room.

The movie model measures 50 feet across, and is lit up by more than 2,500 fiber optic lights. It took 86 people 74 years worth of man-hours to construct -- including building additions as each new film required.

The model itself was used for the aerial shots of Hogwarts, and it was also scanned in 3D for the CGI scenes. It borrows some real-life inspiration from two buildings in the UK: Durham Cathedral and Alnwick Castle (with some "theatrical exaggeration," of course.)

Harry Potter Studio Tour London opens March 31st.
