Polish Post Office (Danzig)
post office
The Polish Post Office (Poczta Polska) in the Free City of Danzig (modern day Gdańsk) was created in 1920 and operated until the German invasion of Poland that marked the beginning of World War II.
History
The post office was established in Danzig under the provisions of the Treaty of Versailles, and its buildings were considered extraterritorial Polish property.
The Polish Post Office in Danzig comprised several buildings, originally built as a German military hospital. In 1930 the "Gdańsk 1" building on Hevelius Platz (square) in the Danziger Altstadt (Old Town) became the primary Polish post office, with a direct telephone line to Poland. In 1939 it employed slightly over 100 people. Some employees at the Polish Post Office belonged to a self-defence and security organization, and many were also members of the Polish Związek Strzelecki (Riflemen's Association). According to the testimony of Edmund Charaszkiewicz, the Polish Post Office was from 1935 an important component of the Polish Intelligence organization, "Group Zygmunt".
As tensions between Poland and Germany grew, in April 1939 the Polish High Command detached combat engineer and Army Reserve Sublieutenant (or 2LT) Konrad Guderski to the Baltic Sea coast. With Alfons Flisykowski and others, he helped organize the official and volunteer security staff at the Polish Post Office in Danzig, and prepare them for eventual hostilities. In addition to training the staff, he prepared the defenses in and around the building: nearby trees were removed and the entrance was fortified. In mid-August, ten additional employees were sent to the post office from Polish Post offices in Gdynia and Bydgoszcz (mostly reserve non-commissioned officers).
This brief starts where responsible research should: with the source description of “Polish Post Office (Danzig)” as post office. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as post office. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 9, 2026. The linked authority identifier is Q564399. VIAF identifies the subject as 90156009847849581018. Authority coordinates are 54.355, 18.657. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1920, 1930, 1939 and 1935.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
