Kłączno (de|Ulrichsdorf)[1] is a village in Gmina Studzienice, Bytów County, Pomeranian Voivodeship, in northern Poland, approximately 11km (07miles) southeast of Bytów and 780NaN0 southwest of the regional capital Gdańsk. It is located on the western shore of Kłączno Lake in the region of Kashubia.
In 1939, the Germans carried out arrests of local Polish activists, whereas a local Polish teacher was captured and murdered by the invading Germans near Kościerzyna (see Nazi crimes against the Polish nation).[2] [3]
From 1975 to 1998 Kłączno was administratively located in Słupsk Voivodeship.
