Reminder: all indoor sports activities remain available, and Poseidon remains open.
The whole team wishes you a great time at POSEIDON!


Eric Bott, alderman for sports, President of Poseidon
We would like to inform our users that, from Monday 27 April, access to the building will no longer be possible via the main entrance.
Access to the various facilities (Sports Hall, Climbing Wall, Studio) will now only be via the sports hall.
We therefore ask all users to use this entrance to access their activities.
In addition, a temporary payment desk will be set up near the entrance to the multi-sports hall (the exact location is yet to be confirmed) to enable on-site payment for activities.
We are aware of the inconvenience this situation may cause and are doing everything we can to improve access as soon as possible.
Thank you for your understanding.
Dear Clients,
Due to maintenance work, the swimming pool will be closed starting January 5, 2026, for an estimated period of approximately six months.
The complex will remain open for all indoor activities, which will continue as usual.
Thank you for your understanding.
Kind regards,
The Poséidon Team
