Tombstones

A headstone, tombstone, or gravestone is a stele or marker, usually stone, that is placed over a grave. They are traditional for burials in the Christian, Jewish and Muslim religions, among others. In most cases they have the deceased's name, date of birth, and date of death inscribed on them, along with a personal message, or prayer, but they may contain pieces of funerary art, especially details in stone relief. In many parts of Europe insetting a photograph of the deceased in a frame is very common.

The stele (plural stelae), as it is called in an archaeological context, is one of the oldest forms of funerary art. Originally, a tombstone was the stone lid of a stone coffin, or the coffin itself, and a gravestone was the stone slab that was laid over a grave. Now all three terms are also used for markers placed at the head of the grave. Some graves in the 18th century also contained footstones to demarcate the foot end of the grave. This sometimes developed into full kerb sets that marked the whole perimeter of the grave. Footstones were rarely annotated with more than the deceased's initials and year of death, and sometimes a memorial mason and plot reference number. Many cemeteries and churchyards have removed those extra stones to ease grass cutting by machine mower. Note that in some UK cemeteries the principal, and indeed only, marker is placed at the foot of the grave.

Owing to soil movement and Downhill creep on gentle slopes, older headstones and footstones can often be found tilted at an angle. Over time, this movement can result in the stones being sited several metres away from their original location.

Graves, and any related memorials are a focus for mourning and remembrance. The names of relatives are often added to a gravestone over the years, so that one marker may chronicle the passing of an entire family spread over decades. Since gravestones and a plot in a cemetery or churchyard cost money, they are also a symbol of wealth or prominence in a community. Some gravestones were even commissioned and erected to their own memory by people who were still living, as a testament to their wealth and status. In a Christian context, the very wealthy often erected elaborate memorials within churches rather than having simply external gravestones. Crematoria frequently offer similar alternatives to families who do not have a grave to mark, but who want a focus for their mourning and for remembrance. Carved or cast commemorative plaques inside the crematorium for example may serve this purpose.
