Built in 1912, this squat grey structure exudes oodles of charm, thanks largely to the two bulbous domes poking cheekily up from either side of the façade. It’s only when you move round the side of the church and see the Star of David motifs adorning the outer walls that you realise that this is Donji Grad’s former synagogue. Jews made up 8% of Osijek’s population prior to their extermination by the Nazis. Their main synagogue, opposite the town hall in Gornji Grad, was demolished by Croatian quislings in World War II.
