Heeresversuchsanstalt Peenemünde
The Koserow Observation Tower was a Wehrmacht observation tower on the Streckelsberg built in the late 1930s for observers of air raids (e.g., on the ports of Swinemünde and Szczecin). The tower's observation deck later had a cinetheodolite for the optical tracking of missile tests from Peenemünde-West (e.g., V-1 flying bomb) and the Peenemünde Army Research Center (V-2 rocket).
