Evangelicals

There is not much data on Germans - former inhabitants of Sejny. It is only known from the statistics that in 1913 there were 93 of them, which made 2,82 percent of Sejny population. "Przegląd Polski" (1875) gives yet another numbers: according to this magazine the Germans consisted 1,2 percent of the population in Sejny county. Evangelic-Augsburg congregation in Sejny was estimated 200 individuals in 1922-23, in 1930 - 350, and in 1938 - 400. 

Evangelical Church members were settled in Sejny in Prussian times. In 1844 at then-called Węgierska street (Hungarian Street) the Evangelic church was built. Jan Mittag served as a pastor between the World Wars. He was also the first mayor of Sejny after First World War. After the Second World War the chapel was retaken by the parson of the Catholic Church parish, who established garrison's Catholic Church.
