Herrnhut belongs to Upper Lusatia – German Oberlausitz, Upper Sorbian Hornja Łužica. The chain of places on this site reads Herrnhut → Görlitz district → Free State of Saxony. Upper Lusatia is stated alongside it, because it is a historical region spanning Saxony, Brandenburg and Poland rather than an administrative unit.
The regional portal keeps its own page about Herrnhut: oberlausitz.com/en/herrnhut. The ‘oberlausitz.’ word mark belongs to Marketing-Gesellschaft Oberlausitz-Niederschlesien; it appears here as a pointer to that portal, not as a sign of sponsorship.
