Where are two places one can find an obelisk constructed during the 20th century?

One place where one can find a Twentieth Century obelisk is the Women's Monument in Bloemfontein, South Africa, which features a statue of two women with depictions of women and children in plaques on either side in honor of the many who lost their lives in concentration camps during the Boer War. Another Twentieth Century obelisk is the San Jacinto Monument in Harris County, Texas, which is topped with a star to show the importance of the location to Texan history.
