Gdyński modernizm lat międzywojennych. Oblicze stylowe epoki = Modernism of the Interwar Period of Gdynia. A Picture of the Style of the Epoch
PublikacjaLata dwudzieste i trzydzieste XX wieku, a więc czas w którym Gdynia powstawała, nie są w historii architektury okresem homogenicznym. Stylistyka modernizmu lat międzywojennych - wbrew swym uniwersalistycznym założeniom ideowym - nosiła w sobie dużą różnorodność. Widzimy to zarówno w odniesieniu do Gdyni, jak i w ogóle do architektury europejskiej tego okresu. Niniejszy rozdział prezentuje cztery główne oblicza architektury modernistycznej...
