Welcome to the Sport Center Poseidon

Dear sports enthusiasts,

Since 1 July 2026, the sports complex and the Poseidon swimming pool in Woluwe-Saint-Lambert have come under direct municipal management, following the takeover of the activities of the former non-profit organisation (ASBL) that previously ran the facilities.

In practical terms, the Sports Department of the Municipality of Woluwe-Saint-Lambert is now directly responsible for managing the site and remains at your disposal for any further information. This change is primarily organisational: the instructors, the sports on offer and the quality of teaching remain unchanged. Only the organisational structure and the registration procedures are changing.

We are confident that this new phase will enable the continued development of the Poseidon sports complex for the benefit of all sports enthusiasts, who will appreciate the quality of the facilities even more.

Important information – Swimming pool closure from 5 January

• Subscriptions & access cards: will be extended with due consideration, at least for the duration of the works.
• Swimming school: further information will be sent directly by email to registered participants. Some classes may take place at Sportcity with the usual instructors.
• Schools: not all schools can be relocated. Swimming lessons are replaced by alternative sports activities (e.g. climbing), supervised by Poseidon and school staff.
• Royal Brussels Poseidon: time slots have been secured in other pools (diving, swimming, water polo). Please contact the club for details.
• Aquagym: most classes are adapted and held indoors with the same instructors during the works.
• Public swimming: residents of Woluwe-Saint-Lambert benefit from the resident rate at Sportcity for the entire duration of the works.
• Residents of Kraainem: no resident rate at Sportcity.
• Duration: starting early January, lasting approximately 12 months.
• Work details:  https://urlr.me/2nGbSh
• PRM accessibility: no PRM lift included in this project (separate project planned for 2026).
• Sauna & jacuzzi: not replaced as part of this renovation (a future wellness area is under consideration).

Reminder: all indoor sports activities remain available, and Poseidon remains open.

⚠️ Important change to access

Poseidon sports complex

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.
