A preserved WWII German “Kugelbunker” (spherical gun bunker) set in calm countryside near Rattersdorf. Photograph the distinctive rounded architecture, weathered details, and narrow apertures against the surrounding trees and sky—especially effective with directional light that sculpts its curved concrete surfaces. Open-air site: no ticketing needed in many cases, but confirm locally.
