Quenzsee
lake in Germany
Quenzsee (Quenz Lake) is a lake in the state of Brandenburg, Germany. It is situated to the west of the city of Brandenburg an der Havel, and is one of a number of directly linked lakes, along with the Breitlingsee, Möserscher See, Plauer See and Wendsee.
The lake has a surface area of 68 hectares (170 acres), and has a maximum depth of 3 metres (9.8 ft).
The lake is navigable and has direct access to the Plauer See, and hence the River Havel, at its western end. The Silo Canal enters the lake at its eastern end. Navigation is administered as part of the Untere Havel–Wasserstraße.
During World War II, a converted mansion at the lake served as a sabotage school for spies who would participate in the failed Operation Pastorius.
This brief starts where responsible research should: with the source description of “Quenzsee” as lake in Germany. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as lake in Germany. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q2122783. Authority coordinates are 52.409, 12.484. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
