Erasmus+ HEROES Project – Day 3 in Brest

11 maart 2026

Our third day brought us beyond Quimper to the coastal city of Brest, just an hour’s drive away, for a full programme of marine discovery, scientific learning and Erasmus+ international exchange.

Océanopolis – SDG 14 Life below water

Our first stop was Océanopolis, Brest’s renowned ocean discovery centre. The pupils were immediately captivated by the enormous aquariums, where large fish drifted towards the glass as if to greet their visitors and the sealions with their amazing ability to carry their bodies speedily through the water with minimum effort. Many of these species live only a few kilometres away in the Atlantic Ocean, offering a powerful reminder of the rich marine life just off the Breton coast.

This visual wonder was paired with hard‑hitting environmental lessons. Exhibits on microplastics and “nurdles”—the tiny plastic pellets that pollute our seas—gave students a confronting look at how damaging human waste can be for marine ecosystems. The message linked perfectly to the HEROES theme and to the work already done earlier in the week on plastic pollution.

During an hour‑long lecture, the pupils discovered fascinating new insights, including that the oceans supply us with around 1,500 distinct medicines and cosmetics. Beyond feeding us, the sea plays a crucial role in healing us too, with several cancer‑fighting treatments originating from marine organisms. This blend of beauty and science left pupils with a deeper appreciation of just how vital our oceans are for human well-being.

Harbour cruise

After Océanopolis, the multinational group boarded a boat for a cruise around Brest’s impressive harbour. Although the local seals and wildlife had seemingly taken the afternoon off, there was no shortage of sights. The French navy provided an unexpected highlight when a group of sailors stood proudly on the hull of their submarine as our boat passed—a moment that sparked both excitement and questions among the pupils.

Even without dolphins or seals, the tour gave the group a unique vantage point on one of France’s most important maritime hubs, further enriching their understanding of the region’s relationship with the sea.

A day of Erasmus+ values

As the pupils returned to Quimper, satisfied and a little tired from the salty sea air. This had been an educational, eye‑opening day, with its mix of marine biology, environmental awareness and intercultural experience. Day 3 embodied the heart of Erasmus+ and TTO values—broadening horizons, opening minds and encouraging young people to view the world through a global and sustainable lens.
