Prussian Poznań: the General-Kommando building and its history

·28 May 2026

The former headquarters of the Prussian 5th Army Corps (German: General-Kommando des V. Armee-Korps) was a highly impressive and stately building, standing out from all the other military structures in 19th- and 20th-century Poznań. It was erected on the site of the former Działowy Square (which no longer exists), at the junction of what are now Działowa and Solna Streets. From the time of its completion in 1889 until 1945, the building served as a reminder of the city’s military might. It was then destroyed and subsequently almost completely demolished.

Poznań as a fortress

Following the Congress of Vienna in 1815, Poznań found itself within the borders of the Kingdom of Prussia, after which it quickly began to transform into a heavily fortified stronghold. Its proximity to the Russian border led to the construction of forts, the Citadel (which we wrote about HERE), barracks and military depots within the city. It was in this setting that the new headquarters of the Prussian 5th Army Corps was built. The building was situated at the northern end of the former Wilhelmstraße, now Aleje Karola Marcinkowskiego. The Poznań Fortifications Office, provisions depots and extensive artillery barracks operated in the vicinity.

The General-Kommando Building

The building was designed in a style inspired by late 19th-century German Neo-Renaissance. The facades, constructed from ceramic and facing bricks, were complemented by details in natural stone. Furthermore, the building was enhanced by decorative gables, pronounced cornices and a central projection, giving the structure a truly palatial appearance. The whole structure was covered by a flat roof, extended only in places. A black-and-white flagpole, visible from a great distance, was mounted on the ridge. The building featured steel-and-brick ceilings and wooden external shutters, considered modern fittings at the time.

Marble, gilding and military ceremony

In front of the entrance to the building, a semi-circular driveway was laid out, surrounded by a wrought-iron fence on a brick foundation. Above the portal was a balcony supported by four columns, and on the eastern side a garden with plane trees was laid out. However, it was the interiors that made the greatest impression, such as the ballroom, which was among the most magnificent in Poznań at the time. Its walls were lined with white marble, the decorations were gilded, and the floors were made of exotic woods. The building housed the headquarters, offices and archives serving a military apparatus numbering several hundred people.

The General-Kommando building in Polish hands

On 22 September 1889, a monument to Emperor Wilhelm I, dedicated to soldiers who fell during the Franco-Prussian War, was unveiled in front of the building. In 1902, two 8.8 cm C73 field guns were also installed there, pointing towards Wilhelmstraße. After our country regained independence in 1918, the building was taken over by the Polish military authorities. From January 1919, it housed the General Headquarters of the Polish Armed Forces of the former Prussian partition, where General Józef Dowbor-Muśnicki and Colonel Władysław Anders, among others, held office. After the Germans occupied the city in 1939, the building was taken over by the Wehrmacht and the Third Reich administration.

Demolition and the last trace of the General-Kommando

The fighting for Poznań in February 1945 left around 55% of the city in ruins. The General-Kommando building was also not spared from the destruction. The roof and interiors suffered the most damage, though the walls remained in a condition that allowed for reconstruction. Despite this, after the war it was decided to demolish the remains of the building, which was not uncommon in Poznań, now once again part of Poland. Buildings of this type were associated with Prussian militarism, which is why the new city authorities often removed or rebuilt architecture symbolically linked to the period of the Partitions. Only the outbuilding located behind the former headquarters building has survived to this day. It is currently used by the University of Arts in Poznań. This is the last physical trace of the historic General-Kommando.
