Prague Day Two

This is the Old Jewish Cemetery, it was founded in the 15th century and closed to new burials in 1787. There are 12,000 tombs on the surface and tens of thousands more in layers underneath. It is such a strange place, the headstones are so close together it is not possible to walk between most of them. And they are all crooked and at funny angles from erosion and subsidence.
Got this off Wikipedia-
Jews must not destroy Jewish graves and in particular it is not allowed to remove the tombstone. This meant that when the cemetery ran out of space and purchasing extra land was impossible, more layers of soil were placed on the existing graves, the old tombstones taken out and placed upon the new layer of soil. This explains why the tombstones in the cemetery are placed so closely to each other.
