The adoption of the Act of 23 September 1922 on the construction of the port of Gdynia by the Polish Parliament is considered the formal beginning of the port of Gdynia. The works on its establishment, however, commenced much earlier.  The favourable international situation, the signing of the Treaty of Versailles and the restoration of Poland’s access to the sea constituted an incentive for the Polish government to take action.

The needs of the Polish trade were to be secured by the Free City of Gdańsk (Wolne Miasto Gdańsk), which was located within the customs area of Poland. The Republic of Poland was granted many rights and privileges related to the use of the commercial port.

In 1920 there was a conflict regarding the blocking of trans-shipment of arms to Poland during the war with Russia, calling Polish warships at port, etc. The need to build the own sea port became apparent. In 1920, the Vice Admiral Kazimierz Porębski, head of the Department of Maritime Affairs at the Ministry of Military Affairs, appointed Mr Wenda, the engineer to choose the place to build a future port.

Mr Wenda not only presented a proposal of the port location, but he also designed it and was appointed the construction manager of the port.
