The Skull Chapel () or St. Bartholomew's Church, is an ossuary chapel located in the Czermna district of Kudowa-Zdrój, Poland. Built in Baroque style in the last quarter of the 18th century, the temple serves as a mass grave with thousands of skulls and skeletal remains adorning its interior walls, floor, ceiling, and foundations. The Skull Chapel is the only such monument in Poland, and one of six in Europe. Read more on Wikipedia
