Sealand Marseilles
A large French marine park with several different marine mammals. (this park is on several maps)

The first Sealand park, located in Argentina opened in late 2020 and proved to be very popular but over the last months with the opening of Sealand Beijing and now, Sealand Marseilles, its visitor attendance plummeted and ticket sales were virtually non-existent, the park was unfortunately forced to close and their animals moved elsewhere, however, the killer whales were moved to Marseilles.
Sealand Marseilles is home to a variety of animals, from the large Killer whale to the tiny Harbor porpoise, Sealand definitely has it all. Inside the park is one of the largest killer whale complexes ever built "Lagune des Orques" which is Orca Lagoon in English. Featuring a huge stadium and six interconnecting pools for the animals to explore, the largest of the five pools is the lagoon which has a large viewing gallery and a small seating area on the top level, overlooking the entirety of the back pools. There are two medical pools, one is exposed and one covered with a canopy, lower than the back pool canopy.

The animals have access to three of the back pools in the complex and the two smaller pools are medical pools for when they are sick or being transported. Currently, the park houses eight killer whales.
The stadium has a curved roof with skylights and has six sections for guests to seat in. On the outside are six access points to the inside, including accessible entrances and the stadium includes a gift shop and refreshments kiosks.

An aerial view of the dining area which features a large glass roof canopy that extends to the edge of the pool, great for those who want to view the whales behind glass to avoid being drenched!
