Several buildings have been built on the island. In the 19th century the navigational beacon Emder Kaap was built. The structure is listed as a national heritage site ("rijksmonument") since 1988 and was moved southwards in 1999. The "vogt" had a house as well; this building was demolished in 1998 due to the encroaching North Sea. In February 2014, the bird observation post was removed from the island. Later in 2014 all remaining buildings on the islands, except for the Emder Kaap, were removed due to the changing shape and position of the island.
