The dead and the mysterious Sarlat lantern

Raised at the end of the 12th century, we don't know who raise that big tower (lanterne des Morts). Is it a funerary chapel?

A building built for the coming of saint Bernard, in 1147 (the legend says he came in Sarlat to bless breads and feed sick persons). Mystery...

But a chronicle written by Jean Tarde in 1561 said a man called Jean del Peyrat was buried "in the cemetery's lantern, which is a chapel, dome-shaped inside and pyramid-shaped outside, located in the middle of the cemetery". Oh, this put us in the picture!
