Schlüsselburg stands in Detern (Landkreis Leer), in Lower Saxony, Germany. No visits are on record for this building.

The Schlüsselburg was a late medieval border stronghold of which no standing remains survive, located in the municipality of Detern in Lower Saxony. Built by the Frisian rural communities to secure their frontier against the County of Oldenburg, it was destroyed and later rebuilt before eventually falling into disuse. Everything known about its layout comes from archaeological excavation and geophysical survey work carried out on the site, which uncovered the moats and a courtyard bordered by three buildings. Nothing is visible above ground today; only the buried archaeological traces remain.

What to know

The site lies within the municipality of Detern, near the route of a bypass road built in the early 2000s.
