ThalNet 2027 will take place at the Aquarium Donostia–San Sebastián, a unique venue located on the waterfront of Donostia–San Sebastián, next to the historic harbour and at the foot of Mount Urgull.
Combining marine science, oceanographic heritage and spectacular views of the sea, the Aquarium provides a distinctive setting for scientific exchange, discussion and interaction.
A unique auditorium
The scientific sessions will be held in the Aquarium’s Auditorium, the venue’s main space for conferences and presentations. The auditorium offers theatre-style seating for 164 participants and features a tropical aquarium measuring 8 metres wide and 5 metres high behind the stage, creating a distinctive backdrop for talks, discussions and scientific exchange.

More than a conference venue
Beyond the scientific programme, participants will have the opportunity to experience one of Donostia–San Sebastián’s most emblematic institutions. The Aquarium combines marine science and maritime heritage with exhibition spaces devoted to ocean life and the maritime history of the region.
One of its highlights is the Oceanarium, featuring an 18-metre glass tunnel surrounded by more than 7,000 fish from 47 different species.
With the sea just outside and marine life forming the backdrop to the scientific programme, the Aquarium offers a particularly distinctive setting for ThalNet 2027.
