Burg Eilsum

Burg Eilsum was a medieval chieftain’s stronghold in the village of Eilsum, part of Krummhörn in Lower Saxony. It stood on a raised mound called a Wurt, which was enlarged to create a separate fortress site. The first known chieftain, Sibrand von Eilsum, held power there in 1370. His nephew Edzard later took control, followed by Imelo Edzardisna in 1400. The Cirksena family eventually gained influence over the site.

The castle occupied the northern edge of the Wurt, with a spur and an added embankment forming its defences. Evidence suggests the main structures were built in the 12th century, first in wood and later in brick. A possible ship landing may have existed in the space between the spur and embankment. The fortress likely protected a nearby harbour.

Today, the site shows little above-ground remains, but the raised Wurt still marks where the castle once stood. Visitors can walk the old embankments and imagine the wooden and brick buildings that once dominated the landscape. The flat marshland around Eilsum stretches in all directions, giving a sense of isolation and historical seclusion. The area remains quiet, with only the wind and occasional birds breaking the silence.
