Medieval Cluj after the great Tartar invasion from 1241, until the Reformation, was a place of the German community. The most important personality of the Reformation in Transylvania was the Lutheran pastor Gáspár Heltai, from the church of St. Michael. Later, a small community of German origin remained in Cluj.
In order to highlight the role that the German community had in Cluj, between the years 1816-1829, an evangelical cathedral was built according to the plans of the architect Georg Winkler, which combines the elements of the neoclassical style with those of the baroque. With a main facade with a width of 18 meters, the church built on 21 December 1989 Boulevard, near Union Square, has a total length of 30 meters and a bell tower of about 40 m.
