The park exists because the new Bundesnachrichtendienst buildings want a clear line of sight. The park exists because it’s a sliver of left-over land through which the south branch of the Panke Canal runs, briefly above ground before being returned to it’s tunnel until it’s spat into the Spree by Bertold-Brecht Str. There is another momentary surfacing behind Deutsches Theater where it dog-legs between the buildings. I have never seen this. It seems to do some right angles to surface in a gully along Schwarzer Weg as well. I think of the Panke as my canal, flowing as it does just beyond the buildings of Uferstudios when I lived in the Uferhallen. I’d always wanted to see where the Südpanke went, but it seemed only underground. Not at all. Between the Spree and BND it flows through a narrow park, one side wetland, the other promenade. Justine showed it to me today as we walked from Naturkundemuseum to Uferhallen, following the stream.
