The National Katyn Monument in Baltimore, also known by the author's title 'Flame of Freedom', pays tribute to the victims of the Katyn Massacre, murdered in the spring of 1940 by the NKVD of at least 21,768 people, including more than 10,000 Polish Army and State Police officers. The monument, unveiled on 19 November 2000, was designed by Andrzej Pityński, an American sculptor of Polish origin. The monument is located on the roundabout between Felicia, President and Aliceanna Streets, opposite the Marriott Hotel "Waterfront" in Baltimore, USA.

The monument takes the form of a bronze sculpture, approximately 20 metres high, depicting golden flames into which are embedded the figures of murdered Polish officers, including Lieutenant Janina Lewandowska, the only woman to die at Katyn. In addition, prominent figures from Polish history are immortalised in the flames, such as Bolesław Chrobry (Bolesław Śmiały), Zawisza Czarny from Garbów, Władysław III Warneńczyk, Jan III Sobieski, Tadeusz Kościuszko, Kazimierz Pułaski, and the Polish emblem.

The artistic use of fire in the monument symbolises rebirth and transformation, and the symbolic fire embraces the martyrs of Katyn, spiritually elevating them to the pantheon of Poland's national heroes. The crowned Polish Eagle emerging from the flames highlights the White Eagle's more than 1,000-year history as Poland's national symbol, whose crown was restored after Poland regained its sovereignty in 1989. The monument also recalls the outstanding figures who have had a significant impact on Poland's history and independence, from the first crowned king, Bolesław Chrobry, through knights such as Zawisza Czarny, to national heroes such as Tadeusz Kościuszko and Kazimierz Pułaski, who also played an important role in the history of the United States.

Thus, the National Katyn Monument in Baltimore is an important symbol of remembrance and respect, linking the history of Poland and the United States, and serving as a space for education and reflection on the past and present of both nations.

The monument's base bears the inscription "KATYÑ 1940". The height of the sculpture itself is approximately 13.4 metres, and together with the granite pedestal, the monument reaches approximately 20 metres in height, making it one of the tallest bronze sculptures on the East Coast of the United States. The casting of the monument was made by the Gliwice Technical Equipment Works.

The idea to commemorate the victims of the Katyn massacre in Baltimore was the brainchild of retired US Army officer Major Clement A. Knefel. The project was financed by the National Katyn Memorial Building Committee, which was formed in 1989 and raised funds for the monument, partly from a special grant from the State of Maryland and charitable donations. The cornerstone of the monument was laid on 29 September 1996, and the unveiling ceremony brought together numerous guests, including Father Zdzislaw Peszkowski and Senator Barbara Mikulski.

The President of the Republic of Poland, Aleksander Kwasniewski, awarded twelve citizens of the United States with the Knight's Cross of the Order of Merit of the Republic of Poland in a decision of 25 October 2000 for their outstanding contribution to the monument. The monument not only commemorates the victims of the Katyn massacre, but has also become the site of annual ceremonies. The National Katyn Monument Foundation operates here, continuing the mission of the Monument Building Committee by conducting educational and memorial activities for the victims of the Katyn massacre.
