Following the route to the sea, we are passing a few architectural "transatlantic ships", including the Housing Complex of Bank Gospodarstwa Krajowego (National Development Bank), called "bankowiec", where it is worth checking the decorations of the staircases, or looking into their "well-holes". It was one of the most modern apartment buildings in the country, equipped, among others, with an underground car park and even an air raid shelter. Inside the building there is a "Mini Museum", founded by the residents themselves. Most of the exhibits are the salvaged elements of the equipment from the apartments, or surviving fragments of decoration, including the famous floor tiles called "corsets". Modernism is present along the entire 10 Lutego Street; The impressive building of the Polish Post Office, and the frontage of four apartment houses numbered 21-27, distinguished by rhythmic glazing.
In Kosciuszki Square, an interesting group of three apartment houses can be found: Peszkowski's, Jurkowski's and Pręczkowski's. At the South Pier, we will meet more jewels of modernism – the Sailor's House with a specific shape (currently the Navigational Faculty of the Maritime University), or – originally built as a Marine Station – Gdynia Aquarium.
