Isern Purt

The Isern Purt consists of four alternating ditches and walls stretching 60 meters in length, with trenches 3-4 meters deep and 10 meters wide.

Built during the Slavic settlement period, this landwehr marked the boundary between German colonizers and Slavic Retharier territory, with earliest mentions dating to 1263.

The structure's name translates from Low German as 'Iron Gate,' reflecting the regional dialect and historical significance of this defensive passage.

Modern visitors can access the site via a marked path from Werder's southern exit, suitable for both cycling and walking through the Rosenholz nature reserve.

The defensive system incorporated natural water features, including lakes, ponds, and swamps, spanning approximately 8000 meters to create an effective medieval border control.
