Ruth Maier's Square is a memorial in Oslo, named after the Jewish refugee Ruth Maier, who was deported and killed during the Holocaust. Maier spent time in a boarding house for young women near the square, and her life and fate have been preserved through a diary published by Jan Erik Vold in 2007. In the pavement by the square, a stumbling stone has been placed in memory of her, which marks her connection to the area.
The square is located at the intersection of Glückstads gate, Dovregata and Krumgata, and serves as an important place for reflection on Maier's life and the historical events she was a part of. Ruth Maier was also a model for the famous artist Gustav Vigeland, and the sculpture "Surprised" was made in her memory. This makes the square a significant point for both locals and visitors who want to learn more about this part of Oslo's history.
