The Ossuary Church is the most impressive church of the small Ustalavic city of Carrion Hill in the otherwise swampland known as the Wrythe. It is located atop the hill in the Crown district. It is run by the priesthood of Pharasma although its site has served many deities over the ages. It is built over countless graveyards and crypts. The building is white and its walls decorated externally with bones harvested from the depths of church's ossuaries. Within the church the walls are decorated with beautiful frescoes depicting Pharasma's Boneyard. The tradition is old, as in the deeper vaults and crypts below, older murals for different gods exist.
