The Evangelical church in Zemun /'Serbia'/ was built in 1926–30 at the corner of Prilaz and Tošin Bunar streets. It was designed by Jewish-Croatian architect Hugo Ehrlich to serve needs of Zemun's Evangelical community at the time mostly consisted of Germans.
Its plan is reminiscent of a trefoil, a rotunda with a prominent east apse and two side wings placed symmetrically in relation to the main entrance. A narrow narthex and the side wings are covered with hip roofs above which rises a larger-sized drum supporting a dome. The lantern mounted on top of the dome originally was surmounted by the cross, a symbol of Christ’s passion.
