The Hauptbahnhof Schneidemühl complex was built between 1851 until the 1876, when the city was part of the Province Posen in the Kingdom of Prussia. By those years, the complex, which included a train depot 430 m. eastwards, became an important part of the Prussian Eastern Railway that connected Berlin with Königsberg, and in the following years new lines were built connecting Piła with Posen, Neustettin, Flatow, Bromberg, Danzig, Frankfurt on the Oder and Wałcz (Gr. Deutsch Krone).
The next model is the Johanniskirche, which didn't have enough luck to survive to these days.
As happens usually with other buildings that do not exist anymore, the geometry work was the easy part. However, looking for other churches with similar caracteristics and some reference pictures was enough to get such a beautiful result. I hope this model to serve as a basis for a future reconstruction in Piła, one day. Enjoy.
