Terra Maris not only has exhibitions inside the building; a landscape garden of 2,5 hectares (6,18 acres) is also part of the museum. There is, for instance, a partial dune landscape, and the remnants of a gully. But there is also a small meadow for sheep, grazing between fruit-trees.A segment of a sea-dike was built in 2007, and shows a normal high-water level, as well as the level of a storm-surge. And there is lots more to discover. Botanists have a lot to enjoy, because characteristic plants are growing in all those different types of landscape. Children are allowed to try and catch the small animals in a pond that is full of life. It is great fun to catch as many different species as possible!
