The interior of the synagogue in Stryków is known from the photo on a postcard from the early 20th century. It shows the central Bimah in the middle of four massive columns as well as parts of the eastern wall.
The vaults above the Bimah columns were decorated with painted Stars of David surmounted with crowns.
The eastern wall was decorated with depictions of the Four Animals, Holy places, and Musical Instruments from Psalm 150. The postcard also allows us the knowledge of the existence of the following paintings:
- The Western Wall in Jerusalem (under the southern window).
- Trees, likely the Tree of Life (between the western wall and the Torah ark).
- A double-headed eagle (between the southern window and the Torah ark, inscribed קל כנשר [Light as the eagle, Pirkeh Avot 5:20]).
- A lion (on northern part of the pictured wall, inscribed וגבור כאריה [Brave as the lion, Pirkeh Avot 5:20]).
- A violin and trumpets (between the eagle and the Torah ark, inscribed הללוה בנבל וכנור [Praise Him with the psaltery and harp, Ps. 150: 3]).
