Actually in modern Germany bodies are only buried for so long. After a period of time, I think it’s ten years or so, the body is dug up and cremated and the plot is reused. They only have so much space.
This has happened in Europe a long time. At least, not keeping bodies permanently. In England some places have long been bringing up bodies and only keeping the skulls for remembrance.
