Maybach I, Military bunker complex in Zossen, Germany.

Maybach I is a bunker complex in Wünsdorf, part of the Zossen command center, built between 1937 and 1940. It consists of twelve houses with artificial roofs, windows and doors, camouflaged as a country house settlement. The bunkers are linked by a ring tunnel, and a south tunnel in the north connects to the Zeppelin communications bunker.

Construction of Maybach I began in 1937 and the last building was finished in 1940. It served as headquarters for most of the Army High Command (OKH) during World War II. In April 1945 the Red Army occupied the site; after the war it was dismantled and partly blown up.

The twelve houses were built with fake roofs, windows and doors so the settlement looked like a country estate from the air. The name Maybach I comes from the Maybach engine works, a cover designation used for the site. Visitors can still see the ring tunnel linking the houses and the South Tunnel toward the Zeppelin communications bunker.

Access is available only through scheduled guided tours organized by local heritage groups. A guide is essential to safely navigate the underground passages and remaining structures.

The bunker facility included self-contained water wells, diesel generators, and air filtration systems designed to protect against chemical weapons. These systems allowed the complex to remain operational even during prolonged attacks.
