A small theatre in Centro Storico, Il Pozzo e Il Pendolo, the Pit and the Pendulum was founded as a mystery theatre in 1999. Today, it has two sections: one dedicated to theatre, the another entirely dedicated to mystery games. Il Pozzo e Il Pendolo also organises a theatre festival at the Botanical Gardens and heads demonstrations, events and shows in Galdo, a medieval village in Cilento.

The games include: Weekend Dinners with Strangers; Crime Cruises; The Game, a game that lasts the entire night and drives Neapolitans crazy; and the Interactive Adventures of Jack, a game that lasts six months. Il Pozzo e Il Pendolo was the first to import Murder Party from England, experimenting and developing numerous variants of it over the years.
