Casa Pia is a Portuguese educational institution founded in 1780 by Queen Maria I after the 1755 Lisbon earthquake to help children and young people at risk of social exclusion or without parental support. For her personal project, Aleksandra Kos worked in the kindergarten class at Casa Pia Belém, assisting the teacher by leading activities to introduce Polish culture, language, and traditions to the students, such as teaching basic English and having the children dance to a traditional Polish children's song.
