Following Soviet admittance of the crime in 1990, the exhumation and archaeological works were resumed. In 1994 a bi-lateral treaty on war cemeteries and war memorials was concluded between Poland and Russia. This paved the way for a construction of a proper war cemetery in Katyn. After several years of construction it was opened to the public on July 28, 2000. That year also similar cemeteries were opened at other mass murder sites of Piatikhatki (near Kharkiv), Smolensk, and Mednoye. The Virtuti Militari awarded to the monument in London was then transferred to Katyn, which became one of the very few places in the world among its recipients.
