In Germany most cemeteries contain only relatively recent grave markers, going back at most one or two generations. This is because families of the deceased typically only rent the graves for a fixed number of years, usually 15-30.
If the family is unable or unwilling to renew the lease, the grave returns to state ownership and the remains are removed and either cremated or moved to a deeper, common gravesite elsewhere.
Because of this cemetery tradition, it is unusual to find examples of very old cemeteries and grave markers. A notable exception is the Historical Cemetery in Flintsbach am Inn, in southern Bavaria. The Flintsbach cemetery has a large collection of old ironwork grave markers, most of them painted in a traditional folk art style. In addition to the unique old iron grave markers, there is a small ossuary housing a handful of skulls.
Know Before You Go
The historical cemetery surrounds the church of St Martin, and can be entered from the church, or through a side gate. The ossuary is in a small building in the back corner of the graveyard.
