Bay of Sielmönken

Map of the Krummhörn around 800 AD

The bay of Sielmönken or Sielmönker Bucht is a former bay in the area of today's municipality of Krummhörn in the west of East Friesland . During the Carolingian Transgression from 800 to 950 AD, the bay reached its greatest extent. It then silted up heavily and was completely surrounded by dikes from AD 1000 to the 13th century .

location

The bay of Sielmönken was located between the Dollart and the Leybucht in what is now the area of the municipality of Krummhörn, and to a small extent also in the area of the municipality of Hinte . In the early Middle Ages it separated the historical landscapes of Emsgau and Federgau .

The first settlers built their houses here on terps in the not yet diked marsh . So they could use the fertile marsh soils and had over the bay and its far-reaching inland creeks access to the sea. Settlement outside the terps was only possible with the construction of the dyke. Locations of the Krummhörn such as Manslagt , Visquard , Jennelt , Uttum , Cirkwehrum , Freepsum , Canum , Pewsum , Woquard and Groothusen trace the course of the historic bay.
