This article focuses on the maritime cultural landscape of the former Zuiderzee ( ad 1170–1932) in the central part of the Netherlands. Since the large-scale reclamations from the sea (1932–1968), many remains have been discovered, revealing a submerged and eroded late medieval maritime culture, represented by lost islands, drowned settlements, cultivated lands, shipwrecks, and consequently socio-economic networks. Especially the north-eastern part of the region, known today as the Noordoostpolder, is testimony to the dynamic battles of the Dutch against the water. By examining physical and immaterial datasets from the region, it is possible to give a modern-day idea of this late medieval maritime cultural landscape. Spatial distribution and densities of late medieval archaeological remains are analysed and compared to historical data and remote sensing results. This interdisciplinary approach has led to the discovery of the remains of the drowned settlement of Fenehuysen.
