L’Aquàrium de Barcelona is the world’s leading aquarium dedicated to the Mediterranean Sea.
To discover it without getting wet, we invite you on a journey that gradually takes you deeper into the sea.
The exhibit features 19 aquariums representing different marine communities and their most characteristic species.
The experience also includes recreations of two iconic protected areas along the Catalan coast: the Ebro Delta and the Medes Islands, both renowned for their outstanding biodiversity.
Discover the richness of the sea
The Largest Marginal Sea on Earth
An Adventure Between Continents
Although the Mediterranean appears to be an enclosed sea, it is connected to other major marine systems through the Strait of Gibraltar, which links it to the Atlantic Ocean, and the Bosporus, which connects it to the Black Sea. Situated between Europe, Africa and Asia, the Mediterranean is one of the most fascinating and diverse marine ecosystems on the planet.
The Mediterranean reaches depths of more than 4,000 metres and is considered relatively poor in nutrients. Nevertheless, it supports extraordinary biodiversity and remarkable ecological richness, including iconic species and large marine predators such as sharks.

Mediterranean Marine Ecosystems
The Mediterranean’s coastlines, seabeds and underwater caves create a remarkable variety of habitats, each with its own unique characteristics. These environments are home to fascinating creatures that spark the curiosity of visitors of all ages.

Explore them in an exclusive way
Each visit is a new opportunity to learn, observe and connect with the sea.
A Strategic Commitment to Biodiversity
The Mediterranean is a particularly vulnerable sea. Its high salinity, rising water temperatures and human pressure along the coastline make it a delicate ecosystem.
For this reason, conserving and studying its habitats—especially the deeper ones—is essential to understanding and protecting marine biodiversity.
We want every visit to be an invitation to learn more about the sea and to inspire greater respect for nature.
