The monumental eelgrass shed on the museum grounds was once used to dry eelgrass. Up till the 1930s, eelgrass was a highly sought after material. It was used, among others, for dike reinforcement, housing insulation and even mattress filling. The wet eelgrass was hung to dry in sheds and later pressed into bales.
The eelgrass shed at Kaap Skil is open for museum visitors. The beachcombing exhibit is presently located in this state monument. Thousands of beach finds are displayed here and the beachcombers introduce visitors to this unusual island tradition.
