A bonehouse is a building, chamber, vault, or other designated space used to store human skeletal remains. It is commonly associated with an ossuary or charnel house, structures created to preserve bones after they have been removed from graves or transferred from earlier burial sites.
Bonehouses have a long history in Europe, particularly in communities where cemetery space was limited. Rather than allowing older graves to occupy land indefinitely, communities sometimes moved the bones of previously buried individuals into a shared structure. This practice made room for new burials while keeping the remains of the dead in a designated place.
The term is especially associated with the German word Beinhaus, which literally means “bone house.” Such structures can be found in historic churchyards, beneath chapels, within crypts, and in separate buildings near religious sites.
Although the sight of human bones arranged in a chamber may seem unusual to modern visitors, bonehouses often reflect the burial customs, religious beliefs, and practical challenges of the communities that created them.
Understanding Ossuaries and Charnel Houses
The words bonehouse, ossuary, and charnel house are closely related, although their usage can vary according to historical and architectural context.
An ossuary is a place or container used to hold human bones. It may take the form of a dedicated room, a chamber beneath a religious building, a burial vault, or a smaller container used to hold skeletal remains.
A charnel house generally refers to a building or chamber used for collecting and storing human bones, often those removed from older graves. Historically, many European charnel houses were associated with churches and cemeteries.
A bonehouse is a straightforward descriptive term for a structure used for the same general purpose. In German-speaking regions, the word Beinhaus is used for such buildings.
These structures were not necessarily designed as places for new burials. Their main purpose was often to accommodate skeletal remains after the original burial site had been reopened or reused.
The terminology can overlap, and the exact designation of a particular site may depend on its architectural form, local tradition, and historical function.
Why Were Bonehouses Built?
One of the most common reasons for creating a bonehouse was the shortage of burial space.
In older European settlements, churchyards often served as the principal burial grounds for local communities. As populations grew and generations continued to use the same cemeteries, available space became increasingly restricted.
In areas where expanding a cemetery was difficult or impossible, communities developed ways to reuse existing graves. After a body had decomposed, the remaining bones could be collected and transferred to a communal storage chamber. The grave could then be prepared for another burial.
This process allowed the community to maintain its burial grounds without continually acquiring additional land.
However, practical considerations were not the only reason for maintaining bonehouses. Religious beliefs also influenced how communities treated human remains. In medieval Christian Europe, charnel houses could form part of broader religious practices associated with prayer, remembrance, death, and beliefs about the afterlife.
Research into medieval charnel houses has shown that these buildings could have religious and ceremonial significance beyond their practical role as repositories for bones.
Consequently, a bonehouse should not be understood simply as a storage facility. Depending on its historical setting, it could also represent a community’s approach to death, memory, and the continued presence of the deceased among the living.
The Historical Development of Bonehouses
Bonehouses and charnel houses developed in different forms across Europe. Many were associated with medieval churches and cemeteries, where the collection and storage of skeletal remains became part of established burial practices.
Some charnel houses were freestanding buildings in churchyards. Others were constructed beneath churches or chapels, sometimes in partially underground chambers.
In certain locations, a chapel occupied the upper level while the bones were kept in a chamber below. This arrangement connected the physical preservation of human remains with religious activities taking place in the same structure.
The practice was particularly useful in communities where burial grounds were small or where religious institutions had served the local population for centuries.
Over time, changing attitudes toward burial, public health, religious practice, and cemetery management affected the use of these structures. Some bonehouses continued to receive remains into modern times, while others became historical monuments or were repurposed.
Today, surviving examples provide valuable evidence of earlier burial traditions. They also help historians and archaeologists understand how communities managed death and burial before modern cemetery systems became widespread.
Hallstatt Bone House in Austria
One of the best-known examples is the Bone House, or Beinhaus, in Hallstatt, Austria. It is located in St. Michael’s Chapel beside the historic Catholic parish church and cemetery.
The ossuary has existed since at least the 12th century. Its distinctive collection contains approximately 1,200 skulls, of which around 610 are painted and decorated.
The collection developed partly because Hallstatt’s cemetery occupies a restricted area, leaving little room for expansion. In the past, graves were often reopened after approximately 10 to 15 years. The skulls and larger bones were then removed and transferred to the ossuary, allowing the burial ground to be reused.
What makes the Hallstatt Bone House particularly distinctive is the tradition of decorating skulls. Many were painted with floral patterns, wreaths, names or initials, and dates associated with the deceased.
These markings helped preserve the identity of individuals and their family connections. The decoration also gave the collection a distinctive appearance, transforming the ossuary into an unusual record of local burial customs.
The tradition of painting and dating skulls began in the early 18th century, although the practice continued into modern times. Some individuals expressed a wish for their remains to be placed in the ossuary, demonstrating that it remained meaningful to the local community.
Hallstatt’s Bone House is therefore both a repository of human remains and a historical expression of how the community remembered its dead.
Bonehouses and Religious Traditions
Throughout medieval Europe, bonehouses were often connected with churches and religious institutions. Their presence reflected the importance of burial grounds in community life and the relationship between religious observance and the treatment of the dead.
In some medieval settings, charnel houses were associated with prayers for the deceased and beliefs about salvation and the afterlife. The remains stored inside were not necessarily viewed as anonymous material. Instead, they could represent members of the community whose lives and deaths remained part of collective religious memory.
The architecture of these structures sometimes reinforced their religious role. A bone chamber might be located beneath a chapel, placing the remains close to a space used for prayer and worship.
The arrangement varied between regions and historical periods. Not every ossuary had a chapel above it, and not every bonehouse served the same ceremonial function. Nevertheless, many surviving structures illustrate how burial practices were shaped by both practical needs and religious ideas.
These traditions also reveal changing perspectives on mortality. The presence of bones within a churchyard or chapel could remind worshippers of the temporary nature of earthly life and the shared fate of human beings.
The Michaelskapelle Ossuary in Oppenheim, Germany
Another notable example is the ossuary beneath Michaelskapelle in Oppenheim, Germany. The chamber is associated with a historical religious complex and is reported to contain the remains of approximately 20,000 people.
Like other European bonehouses, the ossuary reflects the long-term use of burial grounds and the need to accommodate skeletal remains collected over time.
Its scale demonstrates how large communal repositories could become when they served established burial communities over extended periods.
Oppenheim’s ossuary also illustrates the architectural variety of bonehouses. While some examples are separate buildings, others are chambers beneath chapels or churches. These different forms allowed communities to incorporate bone storage into existing religious spaces.
The site provides a reminder that bonehouses were not confined to a single country or architectural tradition. They formed part of a broader European history of burial management, religious practice, and the preservation of human remains.
How Are Human Remains Arranged in a Bonehouse?
The arrangement of bones depends on the structure’s size, purpose, and local tradition.
Some ossuaries contain large quantities of bones placed together in a communal chamber. Others display skulls and larger bones in carefully organised arrangements. In certain historic sites, skulls are positioned in rows or marked with inscriptions, names, dates, or decorative patterns.
The Hallstatt Bone House is especially known for its painted skulls, which preserve aspects of individual identity and family relationships.
Other bonehouses may have little or no decoration. Their primary purpose was simply to keep the remains together in a designated location.
The treatment of skeletal remains also depended on local customs and religious expectations. Some communities placed particular importance on identifying the deceased, while others prioritised orderly storage and the continued availability of cemetery space.
For historians, archaeologists, and visitors, these arrangements offer evidence of how people understood death, remembrance, and communal identity.
Bonehouses as Historical and Cultural Sites
Today, surviving bonehouses are important historical sites. They can attract visitors interested in architecture, archaeology, religious history, and unusual burial traditions.
Their collections provide information about earlier populations and burial customs. In some cases, inscriptions and decorations preserve details about individual people and their families. The structures themselves can also reveal how religious buildings and cemeteries evolved over time.
However, these places are also sites of human remains and often retain religious significance. Visiting them requires respect for the deceased, local customs, and any rules established by the institutions responsible for their care.
Bonehouses are best understood within their historical context rather than simply as unusual or macabre attractions. They demonstrate how communities addressed limited burial space while maintaining cultural and religious connections to the dead.
Conclusion
A bonehouse is a structure used to store human skeletal remains and is closely associated with the terms ossuary and charnel house. These structures developed in many European communities where cemeteries had limited space and older graves needed to be reused.
Beyond their practical purpose, bonehouses often reflected religious beliefs, funeral customs, and traditions of remembering the deceased. Their forms range from freestanding buildings to chambers beneath churches and chapels.
The Bone House in Hallstatt, Austria, is particularly notable for its collection of painted skulls, while the Michaelskapelle ossuary in Oppenheim, Germany, illustrates the scale that communal bone repositories could reach.
Today, these sites preserve an important part of European cultural history. They offer insight into the ways earlier communities managed burial, honoured the dead, and understood the relationship between human remains, memory, and religious life.
