Under the Harbour - WO Assistant checklist

with Mariko Hori

Have you ever wondered what the harbour underwater smells like? Guided by artist Mariko Hori, the participants will experience the Oosterdok in a new light in the workshop Under the Harbour. Thanks to a diving bell system placed at the bottom of the harbour, they will discover the smell of the Oosterdok underwater and transform their personal perceptions of this scent into a melody.

As a workshop assistant, your role is to prepare the materials and the space, take care of ticketing, be there during the workshop and clean up. Don't hesitate to print this assistant checklist and have it with you on the day of workshop!

Here is some information about ticketing when you are a workshop assistant.
