At first glance, the Church of All Saints and Ossuary in Sedlec looks like an ordinary medieval chapel. Its understated exterior offers little indication of what lies inside. The Church of All Saints and Ossuary is one of the most visited monuments in the Czech Republic and is located about an hour east of Prague. It remains a functional Roman Catholic church where masses are celebrated.
In its underground chambers, however, visitors encounter a remarkable sight – the Sedlec Ossuary decorated with the remains of an estimated 40,000 to 70,000 people. Its unusual interior is filled with religious symbolism, intricate craftsmanship and a sobering reminder of the people who once lived and died in the region.
The most striking feature of the Sedlec Ossuary is a massive chandelier suspended in the centre of the chapel. Constructed from human bones, the huge chandelier is said to incorporate at least one of every human bone.
Elsewhere, skulls and bones have been arranged into decorative garlands and other carefully composed displays. One particularly distinctive piece is a coat of arms associated with the Schwarzenberg family, a prominent Bohemian noble family that once held estates in the region.
Its displays reflect centuries-old traditions of contemplating mortality, faith and the afterlife. Around 1400, a Gothic church was built in the center of the exisiting cemetery with a vaulted upper level and a lower chapel used as an ossuary for the mass graves around 1400. This makes it approximately 626 years old.
The site’s history, however, stretches back to 1278, when the abbot of the Cistercian monastery at Sedlec travelled to Jerusalem on the orders of the King of Bohemia. According to local tradition, the abbot returned with soil from Golgotha, the site associated with the crucifixion of Jesus Christ. The soil was scattered across the monastery cemetery, giving the burial ground special religious significance.
Word of the sacred earth spread and people from across the region sought to be buried there. The cemetery eventually became a highly desirable resting place and the number of burials increased.
The cemetery’s popularity was further influenced by the upheavals of the following centuries including outbreaks of plague and conflicts that affected Bohemia. As the burial ground filled, space became increasingly limited.
During the 15th century, a Gothic church was constructed on the site, with an underground chamber used to store human remains removed from the cemetery to make room for additional graves. The bones remained there for centuries before the chapel acquired the distinctive appearance for which it is now known.
The transformation came in 1870, when woodcarver František Rint was commissioned by the Schwarzenberg family to organise the accumulated remains.
Rather than simply storing the bones, Rint arranged them into carefully designed decorative structures, turning the underground chamber into a massive display of bone art. The chandelier, ornamental chains and family coat of arms have become among its most recognisable features.
