Forty thousand human skeletons rest beneath the vaulted ceiling of the Sedlec Ossuary, their bones arranged into chandeliers, chalices, and a coat of arms that took woodcarver František Rint four years to complete. The Schwarzenberg family commissioned Rint in 1870 to impose order on the charnel house that had accumulated beneath the Chapel of All Saints since 1278, when Abbot Heidenreich scattered soil from Golgotha across the Sedlec cemetery. Plague, Hussite wars, and the Black Death filled the grounds. By the sixteenth century, the Gothic chapel could no longer contain the remains. Today the ossuary operates as a conservation site under the Roman Catholic Church, its 220 CZK entrance fee funding structural preservation and climate control systems installed in 2014. The Sedlec complex sits two kilometres north of Kutná Hora's historic centre, itself a UNESCO World Heritage site inscribed in 1995 for its role as the medieval silver-mining capital of Bohemia. The ossuary ticket includes access to the adjacent Cathedral of the Assumption of Our Lady, a High Gothic structure begun in 1290 and restored after Hussite destruction in the fifteenth century. Kutna Hora bone church tickets tours typically combine both monuments with the Italian Court mint and St. Barbara's Cathedral in the town proper. The bone chandelier suspended in the nave contains every bone in the human body. Rint bleached the skeletons with chlorinated lime before assembly, a technique that gives the arrangements their uniform ivory tone. Four pyramidal mounds anchor the chapel corners, each containing approximately twelve thousand bones stacked in alternating femur-skull patterns. The Schwarzenberg coat of arms occupies the left wall—a raven pecking at a Turk's head rendered entirely in phalanges, ribs, and vertebrae. Scholars debate whether Rint intended memento mori symbolism or simply solved a spatial problem with available materials. Visitor flow through the single-chamber ossuary follows a clockwise circuit past the bone structures, interpretive panels in Czech and English explaining the site's eight-century accumulation. The Gothic ribbed vault remains undecorated, directing attention downward to the ossified geometry below. Morning light through the chapel's narrow windows illuminates calcium deposits on the older specimens, evidence of the medieval soil's mineral content.
