Wrangelsburg Castle is a manor house in Wrangelsburg in the Vorpommern-Greifswald district. It was built in 1880 and has been privately owned since 2017.

The current castle was built in 1878. The previous building was converted into a baroque castle in 1652 by Carl Gustav Wrangel, the Swedish general governor of Pomerania. In 1945 it was expropriated and occupied by the Soviet military administration. Today it is in private hands.

The ruins of Oxygen Plant II, one of the two large buildings of the Army Research Institute that have been preserved Around four tons of oxygen burned with four tons of 75 percent alcohol each time an A4 rocket was launched. The first oxygen plant was soon no longer sufficient for the Army Research Institute's increased demand. Oxygen Plant II went into operation in 1942. Production continued until the end of the war, and since then the red brick building has stood as a ruin. At the time of construction, both the technology and the factory were unique in Europe. Oxygen production was based on the Linde process, which breaks air down into its components at -183 °C and liquefies oxygen. The plant was built by specialists from Messer & Co. from Griesheim near Frankfurt. The process was very energy-intensive; the oxygen plant alone required 22 of the 30 kW of the nearby power plant. In continuous operation, up to 13 tons of the oxidizer could be produced daily.

The oxygen plant in Peenemünde is part of what was once the largest military-industrial research complex in Nazi Germany, the former Peenemünde test facilities. Liquid oxygen was produced here to power the A4 unit, also known as Vergeltungswaffe 2 (V2).

The castle is private and not accessible, but walking (not cycling) is allowed on the park paths - it's worth it. A very well-kept facility.

A beautiful castle, albeit simply built from the outside. Today, however, I couldn't see it from the inside. Therefore, only the external impression remains and conveys that a lot still needs to be done.
