Prague’s Old Jewish Cemetery is
actually a 3-centuries-old collection
of burial layers. It was never big enough
to meet the town’s needs, so new
cemeteries were built right on top of
old ones to leave the dead undisturbed,
with graves layered up to 10 deep. Source
sixpenceee, your post on Colma reminded me of Forest Park, Illinois. It’s known as a “village of cemeteries” with it’s dead person to living person ratio being around 30:1. It’s also home to Showman’s Rest, a section of Woodlawn Cemetery where employees of the Hagenbeck-Wallace Circus were buried after a freak train accident in 1918.
