Unusual species of jellyfish, unique crustaceans, and an exhibition built below sea level. We are opening the largest complex in Poland, presenting the environment of the seas of the cold northern hemisphere. Opening on April 20, 2024.
The construction works for the implementation of the new investment in the Gdynia Aquarium started in 2021. From the very beginning, it has been an extraordinary challenge, the effects of which will soon be observable. Over the course of 4 years, an exhibition was created at the Gdynia Aquarium, showcasing the fauna and flora of cold seas. This includes over 30 species of animals, three times the volume of water compared to all of our previous tanks combined, and new experiences for visitors.
Below the surface of the Baltic Sea
The expansion of the educational path for the new exhibition at the Gdynia Aquarium was a challenge from the very first day of construction work. The biggest challenge was the transformation of the existing basement into usable space. This required lowering the foundations and the basement floor, as well as building new column foundations that support the weight of the rotunda structure. Due to the creation of new space below sea level, the contractor had to build a structure resembling a bathtub around the new floor, aimed at protecting the building from water ingress into its interior. Thus, when visiting the “Cold Seas” exhibition, we literally move underwater!
450,000 liters more water!
The new exhibition consists of 12 tanks with a total volume of 450,000 liters! They are inhabited mainly by bony and cartilaginous fish, as well as crustaceans and a species of jellyfish unique to us, Chrysaora quinquecirrha, bred by our aquarists. Visitors will be able to admire the behavior of schooling fish, those that thrive in surf zone conditions, and those that hide in the sand. The entire exhibition presents the fauna of the cold part of the Atlantic Ocean, including the North Sea, the Danish Straits, and the Baltic Sea. Ultimately, up to 1300 new organisms will inhabit the new space.
Cold Seas – from the Atlantic to the Baltic
The new exhibition is designed to showcase the diversity of an environment that is not commonly considered as such. The dynamic, well-oxygenated, and fully salted waters of the northern Atlantic provide excellent conditions for the life of many species of animals and plants. This exhibition is an invitation to embark on a journey that leads from the open waters of the Atlantic Ocean to the nearly enclosed, least saline sea in the world – the Baltic Sea.
Each tank located along the tour route brings visitors closer to discovering a slice of the unique richness of the cold European seas.
The ocean and humanity are inseparably linked
The new exhibition is not only a place where the Atlantic meets the Baltic. It is also a space where guests of the Gdynia Aquarium will be able to learn about the relationships that connect the marine world with the world of humans. The global ocean provides about 50% of the oxygen we breathe, shapes the climate, influences the weather, and is a source of resources that help people live healthily.
The implementation of the project is possible thanks to the support of the Marshal’s Office of the Pomeranian Voivodeship within the framework of action 11.4 of the ROP Pomerania 2014-2020.

What did the investment look like?
This is how our basement looked at the beginning of the investment works.




The arrangement of the exhibition space, in a place previously unprepared for tourists, required a series of construction works. These included:
- reinforcement of the existing building structure,
- lowering of the foundations and basement floor,
- construction of a staircase,
- installation of a new elevator and all necessary utilities.






















In July 2019 the Gdynia Aquarium MIR-PIB and the Foundation for the Development of the Gdynia Aquarium began cooperation with Amber Girl as part of the Save the Sea project. The goal of our cooperation is to raise funds for the purchase of the Seabin device for cleaning Marina Gdynia’s water from solid waste, mainly plastic, and surface pollution. After purchasing and installing the device, the Gdynia Aquarium Education Center will introduce practical educational classes on plastic pollution of the ocean. One of the elements of the classes will be to go outside to empty the Seabin device and to examine what garbage and in what quantity was collected by the device. In addition, garbage removed from Marina Gdynia will be weighted on an ongoing basis, and information on how many kilograms of garbage has been extracted thanks to this project will be available on the website of the Gdynia Aquarium MIR-PIB and in posts published on social media.
Fundraising for our project is done by selling a silver bracelet Save the Sea designed and sold by Amber Girl. The bracelet is made of high quality 925 silver and a rPET string produced from recycled plastic bottles and other consumer post and industrial PET waste. The main silver element of the bracelet refers to the coat of arms of Gdynia and is designed to unite everyone interested in the fate of the Baltic Sea. In addition to financial support for the purchase of a Seabin device, the bracelet is also educational. By creating a recognizable symbol of social responsibility, we can contribute to the development of ecological awareness not only in the target group, but also outside of it. The bracelet itself and the packaging (glass bottle filled with amber, wooden chips, cardboard box and ecological protective envelopes) are consistent with the idea of the design. The bracelet will be sold via the Amber Girl website. All proceeds from the sale will be donated to the Gdynia Aquarium Development Foundation for the purchase of the Seabin device.
