The monument was erected in 1982 to commemorate an event which took place a hundred years earlier. During the years 1871 – 1873 Wojciech Kętrzyński was staying in Pomerania discovering some valuable archival materials in Radzyń Chełmiński, Golub and Chełmno. From his discoveries he gathered materials which he used later in his work “O ludności polskiej w Prusiech niegdyś krzyżackich”, printed in Lviv in 1882.
