A cemetery is any place with graves, tombs and memorials. The range of types and appearances is vast, from extensive mausolea with huge architectural elaborations, to unmarked plots of ground with hardly a sign it is a resting place.
In some cases royal memorials and tombs (see monarchies) may be the central point of vast grounds that might not always be known as a cemetery as such. Such sites are extensively visited for a wide range of reasons, depending on the local or national culture, they might be pilgrimage sites as well.
Some countries have extensive pilgrimage systems. Cemeteries and the tombs of special people within a religious or national context are connected with others. Sometimes the networks are well mapped and signed, others more mysterious and less obvious.
To complicate the issue, some areas and places have very different ideas about pilgrimage, and deny the veracity of the process. People can be told 'no there is no special grave here', or even directed to not consider graves or tombs to be suitable to visit at all.
The important part of becoming involved in pilgrimage is to research first. To make sure the cemetery or tomb is an acceptable place to visit and that there are no prohibitions.
Some grave complexes have elaborate procedures for visitors to comply with, with restrictions on visiting times, and clothing. In some countries, where hierarchical social and political strictures exist, some graves can even be off limits, or distanced from public access.
Some cemeteries in built up areas have massive walls and fences for protection from vandalism. The walls and the surrounding structures can say more about the history of the location than the actual tombs.
In earlier times the walls and structures surrounding may have been built in relation to beliefs about things leaving the cemetery, as much as entering.
The leave-no-trace principle is the same as for archaeological sites. The legal consequences for trespassing in restricted areas, damaging graves, or souveniring artifacts from graves might be harsh. Respect the laws and regulations of local authorities.
Some cultures have very distinct beliefs about how or how not to visit graves, and it is well worth checking out acceptable practices.
For instance some places have strict rules on not walking over or touching a grave or its coverings.
Some places also have specified clothing types for people entering, in most cases pieces of clothing are available to hire at entries, or items considered not suitable can be kept at the entrances.
Avoid taking photographs of grieving people.
Some cemeteries have custodians or caretakers who have information about the place or know where information can be found.
Some cemeteries have museums, organised tours and guidebooks for tourists to find the graves of famous and significant people.
Many older cemeteries and grave sites that are archaeological sites as well.
Due to the pressures of genealogical enthusiasms some cemeteries are able to provide burial lists and details.
However, weathering of gravestones or headstones can wash away all information, and for some places, the site is so old, there are simply no people or publications available about the deceased buried there.
The opportunity to be 'on site' during an important person's funeral or funeral procession can be a very special insight into a country or culture's attitude to people and their death.
High status people in some countries have such elaborate funerals that to be a witness is something that is very memorable.
There are usually protocols as to how close to death the funeral process is held, some events of burial are very close to death. Others require delays in numerical or calendrical auspiciousness.
Included in the protocols are the orders of precedence who precedes who in the sequence of mourners, some mausoleums and cemeteries have illustrations of the mourning processions of earlier deaths, where each allocated position in the mourning procession is identified.
There are limited ranges of cemetery souvenirs: usually guide books. Some cemeteries have meticulous and elaborate guides.
