The vast construction of rustic stone buildings with granite foundations was built at a cost of 20 million Reichsmarks, and the facility was officially dedicated on 24 April 1936.

On 16 May 1941, the Ordensburg was renamed "Die Falkenburg am Krössinsee" (The Falcon Castle at Lake Krössin) by the Reichs Minister of Labor, Dr. Robert Ley.

Cadets, known as Ordens Junkers, were required to be at least 5 feet 4 inches (1.63 m), between 23 and 26 years old, racially pure and in good health without any physical limitations.

These boys between 12–18 years old eventually became the sole occupants of all three Order Castles with the invasion of Poland in 1939 and the start of World War II.

Although the archeologists had long known that the time capsule was buried in the building foundation, they were not able to access it until 2016, and had to wade through groundwater, cut through thick concrete and evade potential German mines in order to reach it.
