An icon of Protestantism in Hungary, the church has earned the city the nickname "the Calvinist Rome".
In 1640–1642 a tower was constructed and a large bell – about 300 kg, made of Austrian cannonballs – was placed in it.
In 1707, during the freedom fight led by Francis II Rákóczi the church suffered heavy damages from the imperial troops.
It was designed by Mihály Péchy, but the plans were altered several times during the construction, causing much frustration to the builders.
Originally a dome was planned to crown the building, this was not built, but when the construction was finished, the facade seemed unattractive with the large empty space between the towers, so in 1823/24 the facade was slightly modified, using the plans of Károly Rábl.
This is a new, electronic organ with resonance pipes, three manuals and 52 registers, built by Péter Albert in 1981.
