In 2024, a new seal rescue center named the World Heritage Center (WEC) opened in Lauwersoog, in the north of the Netherlands. This new center is near the Wadden Sea, a protected area listed by UNESCO. A young gray seal named Witje was rescued and brought to the center. Witje had a swollen flipper and a hurt eye. The WEC replaced the old Pieterburen Seal Center, which opened in 1971. The new center is closer to the sea, so seals can recover in a natural place. A study by Wageningen University showed that about 24,000 seals live in the Wadden Sea. Around 200 seals are rescued each year. They are often injured by trash in the sea, boat accidents, or are separated from their mothers.

At the WEC, seals are put in seawater tanks to help their healing. The salt water helps their skin and fur stay clean. The center has 12 care rooms that are cleaned often. It cost over 40 million euros. It also teaches people about the sea. The center promotes awareness, ecology, conservation, importance, and healing.
