D block was the dominion of modern languages. German, French, and latterly Spanish. The school had twinning arrangements with schools in a least two of these countries and I recall children from Kamen in Germany coming to visit and accompany their “twins” in lessons. I have no idea what they made of black country accents, or the area of Sandwell in general come to that!
German was on the lower level and French up a flight of stairs.
D block always reminded me of going on holiday- waiting in the departure lounge for the teachers to turn up, and the day dreaming of far away beaches. I never quite got there, or had much time for the languages either but there was something quite endearing about the block nonetheless.
