This was what happened in the Old Jewish Cemetery, in the Jewish Quarter of Prague.
Not once, or twice, but twelve times.
The Old Jewish Cemetery is among the oldest surviving Jewish burial grounds in the world.
It was founded in the early 15th century, with the oldest gravestone dating back to 1439.
The last burial took place in 1787.
Today there are 12,000 tombstones visible in the cemetery tightly packed together fighting for space.
