a giant coat of arms – made of tibias and fibias – is strung up menacingly on the far wall, and a chandelier, constructed from every bone in the human skeleton, dangles in the middle. Until 1870, these bones lay stagnant in the ossuary when a local woodcarver, Frantisek Rindt, was given the task of arranging them. No one quite expected the result – a kind of spooky skeletal art gallery.
