In the 1930s, the facade of the Main Synagogue was repaired. The community decided to conceive it as a symbol, this time of modern Czechoslovak Judaism.
A competition for young architects was won by Oskar Oehler and Elly Oehler-Sonnenschein, and in 1934 the Moorish pseudo-oriental style, typical of synagogues in Austria-Hungary, disappeared from the facade and Ostrava could boast a synagogue with a completely modern facade.
