The Seven Seas Stadium is the location of the 2019 MarbleLympics.
Construction began in late 2017 and continued while the Oceanics participated in the 2018 MarbleLympics. Queen Marina and her subject, Alvin, supervised construction during this time. To thank him for helping, Coach Tide named Alvin the mascot of the Oceanics when he returned with the team.
The Oceanics began practicing in the stadium as construction entered its final phase, during the offseason of the 2018 season. At the end of the A-maze-ing Marble Race, the Oceanics were selected as hosts.
Construction wrapped up on the stadium in January 2019, a few weeks prior to the Qualifiers. It was used for the 2019 MarbleLympics Qualifiers as well as the Friendly Round. It was also used through the whole 2019 MarbleLympics and will be used for the MarbleLympics Showdown 2019.
- This is the first MarbleLympic stadium with two levels, as well as the first with a canopy.
- The name of the stadium was suggested by a fan prior to Qualifiers and was then chosen after fan voting.
