Mae'r cysylltiadau rhwng Cymru a Birmingham yn llawn hanes ac yn deillio o ymateb y cyhoedd yng Nghymru i’r bomio ar 15 Medi 1963 lle cafodd pedair merch ifanc ddu eu llofruddio a chafodd yr eglwys ddifrod mawr. Fel arwydd o undod gyda'r gymuned Affricanaidd-Americanaidd yn Birmingham, cododd pobl Cymru arian ar gyfer creu ffenestr wydr lliw ar gyfer yr eglwys, a ddyluniwyd gan yr artist Cymreig John Petts gan ddarlunio Crist croeshoeliedig du. Cafodd 'Ffenestr Cymru' ei chysegru ym 1965 ac mae'n dal yn rhan ganolog o gymuned Eglwys y Bedyddwyr 16th Street. Roedd cyfraniad Cymru i'r seremoni hefyd yn ein galluogi i dalu teyrnged i waddol parhaus yr ymgyrch dros gyfiawnder hiliol yr oedd Birmingham mor flaenllaw wrth ei hyrwyddo, a myfyrio ar y ffordd y mae eu haberthau wedi ysbrydoli pobl o liw ar draws y byd, gan gynnwys yma yng Nghymru.
The links between Wales and Birmingham are steeped in history and stem from the Welsh public’s response to the bombing on 15 September 1963 in which four young black girls were murdered and the church suffered significant damage. As a gesture of solidarity with the African American community in Birmingham, the people of Wales raised funds for the creation of a stained-glass window for the church, designed by Welsh artist John Petts and depicting a black crucified Christ. The ‘Wales Window’ was dedicated in 1965 and is still a central part of the 16thStreet Baptist Church community.  The Welsh contribution to the ceremony also allowed us to pay tribute to the enduring legacy of the campaign for racial justice that Birmingham was so prominent in advancing and to reflect upon the way in which their sacrifices have inspired people of colour across the world, including here in Wales.
