 The village of Oterdum which was built against an older section of sea dike was flooded occasionally by storms and was demolished in the 1970s for raising the dike elevation.Coffins traditionally buried in the old dike were moved to Farmsum, leaving monuments in the enlarged dike to commemorate the village and cemetery.A few Kilometers farther down the coast are the villages of Borgsweer and Termunten that give some idea of the traditional land use before industrial expansion.
