  • About


    We set out to blur the lines of believability and create an alternate reality you can walk into and interact with. Collaboration between performers and designers is core to our process. Through a synthesis of improvisation, devising, and written text, we create spatial narratives and the characters who inhabit them.

    “The best immersive theatre I’ve seen in a very long time…You must see this – it’s a terrific example of site-specific immersive theatre, and even the most un-theatrey person you know will love it.”

    “Immer City are perfectionists. From the moment you arrive at an undisclosed location in Southwark you are completely swept up in the confusion of who is and who isn’t part of the production. Secrecy and mystery are key.”

    “…the performance was fascinating because it had a surprisingly powerful effect on many members of the audience and sparked a tremendously interesting debate about humanity and conformity…it is a very stimulating and unique experience.”
