For the past 18 Halloweens, students at the New York City College of Technology have designed, built, and operated the Gravesend Inn, a theme park-esque haunted hotel that grows more frightening each year.

The annual attraction is produced by Theatreworks, the college's resident theatre troupe. Volunteers from CityTech's students and faculty are responsible for constructing and operating the hotel, and even for performing as ghouls, zombies, and more within its walls. The hotel itself is almost entirely automated, with all of its effects triggered by audience interactions, but it still takes about 20 students from CityTech's Entertainment Technology Department to run the show behind the scenes.

Photographer Tod Seelie told Gothamist that the audience is rewarded with "a unique surprise" once they make it through the house—but he didn't give it away. If you'd like to find out what your reward is, head to the Voorhees Theatre in Downtown Brooklyn (despite its name, the haunted hotel isn't actually located in Gravesend) before Monday, October 31st.

The Gravesend Inn is located at the Voorhees Theatre at 186 Jay Street in Downtown Brooklyn // Various showtimes // Tickets: $5 for students and groups, $10 general admission, free for CityTech students.
