The Protestant Great Church (Hungarian: Nagytemplom) is probably the most well-known building in the city of Debrecen. It stands in the downtown, between Kossuth square and Calvin square. It is the symbol of the Protestant Church in Hungary, and it is because of this church that Debrecen is sometimes referred to as "the Calvinist Rome". With a ground space of 1500 m² it is the largest Protestant church in Hungary. It also has the largest bell of all Hungarian Protestant churches. The Great Church was built between 1805 and 1824 in neoclassical style.
