Perhaps Longa's best known work is her modernist sculpture Shape, Space and Light (1953), positioned at the main entrance of the National Museum of Fine Arts in Havana.
[1][2] On the initiative of Rita Longa, the city, Las Tunas, in southeast Cuba, which she considered her second home, erected more than 125 public works of art.
Her bronze statue of Jose Marti, the Apostle of Cuban Independence, situated in the plaza bearing his name, doubles as a solar clock.
[3] She also has works all over Havana—at the National Zoo (“Family Group”), the Colón Cemetery, the Museum of Fine Arts (Shape, Space and Light), the Surgical Medical Center, the Payret Theater ("The Muses" and "Illusion"), Havana Libre Hotel (Clepsydra), and the garden of National Theater ("Death of the Swan").
Other countries also hold some of her works like Madrid, Spain (an engraving of Jose Marti) and Belgrade, Serbia (Gema)[4] The sculptor often visited the Zapata Peninsula home of the Taino, Cuba's indigenous people.
