On February 16, 2018, in Linkmenys, near Linkmenai St. Trinity Church solemnly unveiled a monument to the border guards who guarded the Lithuanian-Polish demarcation line in 1923–1939. The monument was erected on the site of the former administrative line with the Polish-occupied Vilnius region. This line was guarded by the Lithuanian Border Police. Officials had to perform a difficult and dangerous service here, as it was a temporary border between the recently warring states. Lithuania never recognized these lines as state borders, but only marked them with simple wooden guidelines, which were often re-examined on the initiative of the Polish and as a result conflicts arose more than once. Our border guards have also suffered as a result.
