A small park with a modern statue of Franz Kafka by Jaroslav Róna is situated between the synagogue and the Church of the Holy Spirit.

The architectural plans were designed by Vojtěch Ignác Ullmann and Josef Niklas (an imposing interior decoration).

Ten years after the war, the synagogue was handed over to the Jewish Museum and in 1958–1959 it was completely restored inside.

In the eastern wall there is a great round stained glass window with a central ornament of Magen David (hexagram), installed in 1882–1883.

Benches (not original, but from synagogue in Zruč nad Sázavou) stand in rows (as in a church), not around the walls.

The European Cantors Association held the concert for their 11th Annual Convention in the Spanish Synagogue in front of a packed crowd on 19 November 2016.

Arranged as a tribute to ECA Convenor, Alex Klein, the concert was led by the Tel Aviv Cantorial Institute Choir conducted by Orthodox Jewish Cantor Naftali Herstik.
