A medieval brick fortress set on an island in the vast Havel river. Climb the Juliana tower for fabulous views of Spandau's centre.
Nearest u-bahn station is Zitadelle on line 7. Just a 10 minute walk down the busy main road between Berlin and Spandau.
Well off the normal Berlin tourist trail - the man in the ticket booth (entrance four euros) says they get mainly German visitors. Closes end of November, over the winter period.
