In the 1960s, a secret complex of the Center of the Council of Ministers' Holiday Center was erected in the village of Arłamów (591 m above sea level) [5]. Jamna Górna became part of the center, which also included villages: Arłamów, Borysławka, Grąziowa, Jamna Dolna, Krajna, Kwaszenina, Łomna and Trójca, in total about 23,000 ha. The center served as a hunting ground for the then party and government elite and their guests not only from "brotherly countries". A special Krajna airport was also built for them near Bircza, where the Arłamów landing ground has been operating since 2012 [4].
