In the years 1863–1864, the Tsarist Army executed 21 leaders and participants of the January Uprising at the Lukiškės Square in Vilnius. In 2017, at Góra Zamkowa, archeologists found the remains of the heroes. Among them, Wincenty Konstanty Kalinowski – leader of the uprising in Lithuania, and the commander of the insurgent units in Samogitia – Zygmunt Sierakowski. As Mateusz Morawiecki highlighted, “The insurgents of the January Uprisings are heroes who unite the nations of Poland and Lithuania and who are still alive in our hearts.”
The ceremonies were also attended by, among others, the presidents of Lithuania and Poland, representatives of Belarus, Ukraine and Latvia, as well as Deputy Marshals of the Sejm and Senate of the Republic of Poland.
The Prime Minister also laid flowers at the Mausoleum of the Mother and the Heart of the Son at the Rasos Cemetery.
