In 2024, the World Heritage Center (WEC) for seal rescue opened in Lauwersoog, a town in the north of the Netherlands. The center is near the Wadden Sea, a UNESCO World Heritage Site. A young gray seal named Witje was brought to the WEC after being found with a swollen flipper and a damaged eye. The WEC replaces the old Pieterburen Seal Center, which started in 1971. The new center is closer to the sea, which helps seals recover in a more natural place. Based on a study by Wageningen University, about 24,000 seals now live in the Wadden Sea. Each year, around 200 seals are brought to the center. Many are injured by trash in the sea, are separated from their mothers, or are hit by boats.

At the WEC, seals are placed in seawater tanks to support their healing. Curator Sander van Dijk explained that the saltwater helps wounds heal faster and keeps their fur healthy. The facility includes 12 intensive-care units that offer a tranquil and safe space for seals to rest. These spaces are cleaned often to avert infection. The center cost over 40 million euros and was supported by public and private donors. It also serves as an educational center with immersive exhibits. The goal is to raise awareness of the Wadden Sea’s ecological value and promote conservation actions.
