Yn dilyn y bomio, a oedd yn foment allweddol yn Mudiad Hawliau Sifil yr Unol Daleithiau, ariannodd pobl Cymru ffenestr gwydr lliw newydd yn darlunio Crist du ar y groes fel arwydd symbolaidd o undod. Wedi'i ddylunio gan yr artist Cymreig John Petts a'i gefnogi gan ymgyrch gan y Western Mail, rhoddwyd 'Ffenestr Cymru' i Eglwys y Bedyddwyr 16th Street.
Following the 1963 bombing, which was a pivotal moment in the US civil rights movement, the people of Wales collectively funded the creation of a unique stained-glass window to aid reconstruction efforts at a church that was a focal point for activism. With its powerful depiction of a black Christ on the crucifix, the window has, for decades, served as a moving symbol of solidarity. Designed by Welsh artist John Petts and supported by a fundraising campaign led by the Western Mail, the ‘Wales Window’ was gifted to the 16th Street Baptist Church in 1965.
