In the evening on Saturday 25 October 2025, the American Library in Paris will turn into a Haunted Library, with guided tours throughout the dark, and winding Library stacks. Grab your bravest friends, and explore the Library as you’ve never seen it before. Tours last 15-20 minutes, and must be booked in advance. Games will be available in the Library’s Reading Room before and after tours.

All Haunted Library guests are invited to join the finale, from 20h00-20h30, which will include a spooky performance by members of the improvisational theater company The Improfessionals. The group has performed more that 150 shows in Paris and around the world. Their new improvised musical comedy is showing now in Paris, with performances in English. The Haunted Library will culminate in a costume contest. First, second, and third prize costume prizes will be awarded. The costume judges are always especially impressed by homemade costumes, and creative ensembles.

Light refreshments will be provided by the Library.

This event is intended to offer surprises and scares for older children, teens, and adults. If your child is easily frightened, please consider purchasing tickets for the Halloween Extravaganza Monster Mash at 15h00. You may be interested in trick-or-treating (no registration required: details here).
