Poznań, Greater Poland
The Poznań June 1956 Monument, known locally as the Poznań Crosses (Poznańskie Krzyże), stands on Adam Mickiewicz Square in the city's Imperial District, next to the Imperial Castle. Two joined steel crosses, 19.5 m and 21 m tall and bound with a carved rope, commemorate the victims of the first mass revolt against communist rule in Poland and of later protests in 1968, 1970, 1976, 1980 and 1981. It is free, open around the clock and essential for understanding modern Poznań.
On the morning of June 28, 1956, remembered as "Black Thursday," workers at the Cegielski engineering works (then named after Stalin) went on strike. Their march swelled to nearly 100,000 people outside the city authorities' offices in the Imperial Castle, and demands for bread and fair pay turned into anti-government and anti-Soviet slogans. The regime sent in roughly 10,000 soldiers and hundreds of tanks. Dozens were killed (counts vary, a total of 57 is often given), including 13-year-old Romek Strzałkowski, who became the symbol of the tragedy. It was the first general strike in communist Poland, and it helped trigger the political thaw of October 1956, the same year as the Hungarian Revolution.
The idea came from the Solidarity movement in autumn 1980. Sculptor Adam Graczyk and architect Włodzimierz Wojciechowski won the design competition, and the steel parts were made largely at the Cegielski plant, where the 1956 protest began. The monument was unveiled on June 28, 1981, the 25th anniversary, before a crowd of about 200,000; Lech Wałęsa was among the speakers. Half a year later martial law was declared.
The main anniversary ceremony takes place here every June 28.
The neo-Romanesque Imperial Castle, built for Kaiser Wilhelm II, houses the Poznań Uprising – June 1956 Museum (check current hours before you go). Across the square is the university's Collegium Minus, and close by are the Grand Theater and the Enigma Cipher Center, which tells how Poznań-trained mathematicians first broke the German Enigma code.
