Mazowiecki, who died in 2013, was Poland’s first non-communist prime minister after World War II. He made his policy address to Parliament 30 years ago.
The unveiling ceremony was attended by Mazowiecki’s two sons with their families and former President Bronisław Komorowski, who called Mazowiecki “a general in the difficult struggle for Poland’s future, for a free, independent and sovereign Poland.”
Komorowski added that it is thanks to people like Mazowiecki that Poland is now "in the family of democratic states."
The 2-metre high monument to Mazowiecki, cast in bronze, stands close to a high school which he attended.
Mazowiecki served as prime minister from August 1989 to January 1991. He died on October 28, 2013, at the age of 86.
