Having passed the test, the Haunted Castle was assembled on a new site in 1979, consisting of seventeen interconnected aluminum trailers leased from same manufacturer—eight to a side mirroring each other—with separate corridors and a common control room in the center. The castle's trailers were linked by plywood partitions to create a complex maze. The interiors were built of plywood walls and ceilings with wooden studs for support. The materials used on the walls included foam rubber, various fabrics and plastics, plywood and tar paper. Wax mannequins were used as props. Attached to its exterior were painted turrets and towers of plywood on wooden frames intended to emulate a medieval façade.
