Eemnes (Dutch pronunciation: [eːmˈnɛs] ⓘ) is a municipality and a village in the Netherlands, in the province of Utrecht.

These names referred to the location of the villages with respect to the dyke of the river Eem.

Dutch topographic map of the municipality of Eemnes, June 2015 Until 1932, when the Afsluitdijk sealed off the Zuiderzee from the North Sea, the weak dykes in this part of the country would occasionally break during storms.

Because they could be tens of meters in diameter and several metres deep, landowners often did not make the effort of filling them up.

Because they symbolize man's battle against the sea and are relatively rare, provincial authorities designated them "geological monuments" in June 2005.
