REBECA, short for REunion and Bengal Engineering College Annuals, is the cultural fest of IIEST, Shibpur. Bengal Engineering College is the old avatar of IIEST, Shibpur. Rebeca is the oldest Cultural Fest in the whole of India. For an entire year, the students look forward to these 4 days of absolute ecstasy. Drawing artists and performers from the city, the state and the nation, REBECA isn't just another college fest. It's a culmination of the emotions and nostalgia of the most profound Alumni Base in the country.

The event is divided into four days a) Classical Night: A treat for classical music connoisseurs b) BEings Night: The stage is set for BEings (current students) to rock the stage c) Kolkata Night: A night of Bengali music. Even if you don't know the language, you can still enjoy the night. d) Mumbai Night: The best night of it all. If you are a final year student, it will the saddest one actually.
