Artist Bruno van den Elshout is holding his 21st 24-hour horizon observation on Zuiderstrand on Tuesday, 22 September. The event brings together up to 24 participants, each seated on their own chair along the tide line with appropriate distance between them.
The gathering begins shortly before sunset on Tuesday and ends at sunset on Wednesday, 23 September. A campfire will burn for the full 24 hours on the beach.
Rules on the sand
Participants are expected to spend the day watching the sea and reflecting. Sleeping is discouraged, and long conversations are not allowed, though attendees may briefly talk or ask a neighbour to share food.
People are free to stand up, stretch, walk along the beach, visit a beach pavilion, or go for a swim during the day.
Origin and registration
The concept began in 2013, when Van den Elshout photographed the North Sea horizon every hour for a year for his project New Horizons. After completing the first 24-hour session alone, he began inviting others to join, with around 120 people taking part across previous editions.
Registration closes at 09:00 on Monday, 14 September. Participation costs 144 euros, which includes a group photograph, and signups are handled through 24-uurshorizonobservatie.nl.
